1. Introduction

Minecraft Basic is the first and only BASIC interpreter available for Redpower Control. The historical Microsoft Basic 6502 code was compiled and improved by BiGFoot to be made to work on the RPC8 computer. Many enhancements were also added such as a file system and full support for IO Expanders and external hardware. It even includes an optional enhanced boot loader enabling a faster bootup sequence. Programming in BASIC is easy . It allows you to program with little effort while getting big results. BASIC can be used as an alternative operating system solution for the RPC8.

 2. Installing BASIC in Minecraft Redpower Control

  1. Insert and boot the blue Forth Disk
  2. When Mine OS has loaded insert a blank floppy into the drive,
  3. Type SAVE” BASIC” into the terminal, then type DISKID to print out the disk ID of the blank floppy. Take note of the disk ID. 
  4.  Minimize the game window and locate the “redpower” folder of your current world save. Macintosh Users:  ~/Library/Application Support/minecraft/saves/savename/redpower/ Windows Users: %appdata%/minecraft/saves/savename/redpower/
  5. Find a file ending with .img which has the DISK ID that you took note of in step 3.
  6. Download the latest BASIC img from  and rename the file so that it matches the generated img in the redpower folder 
  7. Drag the file into the redpower folder and overwrite the file. If prompted to overwrite the file answer “Yes”. 
  8. Log back into the game and start with a fresh computer, make sure to add at least 1 module of 8k RAM or BASIC won’t run. 
  9. Boot the BASIC yellow floppy disk, if everything went well you should see the start up  message after a few seconds.

Congratulations you’ve successfully installed BASIC.

Replacing the default boot loader image for faster booting of BASIC (Optional)

  1. Download “rpcboot.bin” from
  2. Navigate to your Minecraft mod folder and locate the Redpower Control Mod Zip File Macintosh Users: ~/Library/Application Support/minecraft/mods/. Windows: %appdata%/minecraft/mods/
  3. Extract the files in the Zip
  4. Take the rpcboot.bin file that was downloaded from the site and place it in RedpowerControl-2.0pr5b2/elooram/control/
  5. If prompted to overwrite an already existing file answer yes
  6. Select the extracted files and re-compress it into a zip file with the original name, then place it into your mod folder
  7. If everything went well the new boot code should start up and load ms basic immediately.

3. Getting Started

Minecraft MS-Basic is a “standard” BASIC with additional string handling capability and I/O commands, as well as the following features.

Minecraft MS-Basic allows multiple statements per line via “:”. Next without a variable can be used for when FOR-NEXT statements are not nested. END statements are not necessary. Question marks can be used instead of “PRINT”. “LET” is optional. No spaces are required in BASIC. These features allow highly efficient memory usage when necessary.

Variables can be two characters long. Longer variables can be used but only the first two characters will be utilized. The first charter must be alphabetic, the second can be alphabetic or numeric. Long variables can not contain words used by BASIC such as NEW,SIN, and so on. Since spaces are not necessary BASIC would interpret a variable such as “ANEW” as a variable A and the command “NEW” and would erase the program.

Variable Examples:



*Note that variables like AZ1 and AZ2 would be treated the same since BASIC looks only at the first two characters

4. Commands


LIST 100
Lists program

Lists program from line 100. Control C stops
program listing at end of current line.

RUN 200

Starts program execution at first line. All vars
are reset.

Run program from line 200 with variables reset
NEWNEWDeletes current program
CONTCONTContinues program after Control C or STOP if the program has not been modified. For instance a STOP followed by manually printing out variables and then a CONT is a useful procedure in program debugging.
SAVESAVE "PROG"Saves your basic program from memory to disk.
LOADLOAD "PROG"Loads your basic program from disk to memory
DIRDIRShows the disk directory
CLRSCRCLRSCRClears the screen
DISKFORMATDISKFORMAT "MYDISK"Creates MCFS(Minecraft file system) on a blank (or occupied :) disk with name MYDISK
SAVEBASICSAVEBASIC"BASIC"Saves the basic interpreter to the disk
SETBOOTSETBOOT "BOOTME"Sets the boot flag for the file
HELPHELPlists available commands and functions
DELETEDELETE "MYPROGS"Deletes the file (and also remove the boot flag if it's presented on the file)

5. Operators


LET B=10
LET is optional
<>10 IF A<>B THEN 5Not equal
>B>AB greater than A
<BB less than A
< =, =<B<=AB less than or qual to A
=>, >=B=>AB greater than or equal to A
ANDIF B>A AND A>C THEN 7If both expressions are true then--
ORIF B>A OR A>C THEN 7If either expression is true then --
NOTIF NOT B>A THEN 7If B<=A then--

AND, OR, NOT can also be used in Bit manipulation mode for performing Boolean operations of 16 bit 2s complement numbers (-32768 to +32767)

63 AND 16 Result: 16
-1 AND 8 Result: 8
4 OR 2 6 Result: 6
10 OR 10 Result:10
NOT 0 Result: -1
NOT 1 Result: -2

6. Operator Evaluation Rules

Math statements evaluated from left to right with * and / evaluated before + and -. Parentheses explicitly determine order of evaluation.

Precedence for evaluation:

  1. By parentheses
  2. Negation
  3. * /
  4. + -
  5. =, <>, <, >, <=, >=
  6. NOT
  7. AND
  8. OR

7. Statements

In the following examples

V or W is a numeric variable, X is a numeric expression, X$ is a string expression, I or J is a truncated integer

10 DATA 1,3,7 

Data for READ statements must be in order to be read. Strings may be read in DATA statements


10 DEF FNA (V)=V*B

User defined function of one argument


110 DIM A (12) 

Allocates space for Matrices and sets all matrix variables to zero. Non dimensioned variables default to 10


999 END 

Terminates program (optional)


10 FOR X=.1 TO 10 STEP .1
20 ____________

STEP is needed only if X is not incremented by 1. NEXT X is needed only if FOR NEXT loops are nested if not NEXT alone can be used. Variables and functions can be used in FOR statements.

50 GOTO 100 

Jumps to line 100

100 GO SUB 500

500 . . . .

Goes to subroutine, RETURN goes back to next line number after the GOSUB

IF . . . THEN
10 IF X = 5 THEN 5

If the statement is true, then the following will be executed including multiple statements of that line.

IF . . . GOTO

10 IF X=5 GOTO 5

Same as if THEN with line number

ON . . . GOTO

100 ON I GOTO 10, 20, 30

Computed GOTO
If I=1 then 10
If I=2 then 20
If I=3 then 30


20 PRINT “Test”

Prints value of expression. Standard BASIC syntax with , ; ” formats


490 READ V, W

Reads data consecutively from DATA statements in program


10 REM Type some comments here

This is a comment for non executed comments

SETXY valx, valy

10 SETXY 20, 20 

Sets the cursor  to the specified coordinates.


10 DELAY 60

Makes the CPU wait 3 seconds (20 ticks per second) before executing the next instruction.

SETPIXEL valx, valy


puts a pixel at location 10,10 on the screen

CLRPIXEL valx,valy


clears the pixel at location 10,10 on the screen


8. Functions

 ABS (X)
For X=>0 ABS(X)=X
For X<0 ABS(X)=-X

Returns the absolute value of X


Evaluates X for the largest integer


Generates a random number between 0 and 1



Returns 1 if X >0
Returns 0 if X = 0
Returns -1 if exp <0


Sine of X in radians


Consine of X in radians


Tangent of X in radians


Arctangent of expression in radians


Square root of X


Used in print statements to TAB to specified position


Calls the users machine language subroutine with argument I, See section 13 for details.


E to the power of X where E=2.71828


Gives number of bytes left in workspace (X is dummy)


Gives the natural log of X


Returns carriage position of terminal (I is dummy)


Prints I amount of spaces , can only be used in print statements

9. Strings & String Functions

Strings can be from 0 to 255 characters long. All Strings variables end in $. e.g. A$, B9$, HELLO$.

Strings can be dimensioned equated, printed, read from Data statements, etc

To print a string without starting a new line use “;” after of a string
e.g. PRINT “HELLO” ; 


ASC (X$)

Returns the ASCII value of first character in string

CHR$ (I)

Returns 1-char string whose char has ASCII code of I

LEFT$ (X$, I)

Gives left most I characters of string X$


Gives right most I character of string X$

MID $ (X$, I, J)

Returns chars from the middle of the string starting at the position specified (I) to the end of the string or for length characters (J)

LEN (X$)

Returns the length of the string


Converts a numeric expression to a string

VAL (X$) 

Converts the string representation of a number to its numeric value

10. I/O Special Functions

The following features of Minecraft BASIC are useful primarily for I/O control. The user should be extremely  careful with some of these statements and functions since they manipulate the memory of the computer directly. An improper operation with PEEK, POKE,  or SYS can cause a system crash, wiping out BASIC and the users program, thus requiring a complete reload of the computer


Returns  the decimal value of the specified memory of I/O location. (Decimal)

X=PEEK (64256)
will load variable X with the values in address 64256 ( 0xFB00)


Loads memory location I (decimal) with J (decimal). I must be between 0 and 65536 and J must be between 0 and 255.

10 POKE 64256, 255 will load address 0xFB00 with FF(hex)


Read data from the terminal and store result in VAR$


Waits for a character and the result stored in VAL$, works in program mode only
Example: 1 GET A$:IF A$<>”" THEN PRINT ASC(A$)


This will execute machine code at 0×400 (1024 in decimal). Make sure the code ends with an RTS to be able to jump back into basic.
E.g. SYS(1024)


Works like LDA #$J , MMU #$I assembly instructions (yy is 16 bit wide)
E.g. MMUSET0,1 : REM Sets the active redbus device id to 1


Works like MMU #$xx assembly instruction
E.g. MMUGET(129) : REM Reads the redbus window

11. IO Expanders

Minecraft BASIC fully supports IO expanders. By using the values in the chart below with the IO expander functions the corresponding colored redstone wire will light up. 

IO Expander Output Color Values

Light Blue8
Light Gray256
. ID is the number for the IO Expander ID which is set by shift right clicking the hardware with the screwdriver tool

IO Expander Functions


Reads the actual value from IO expander read buffer.


Reads the actual value from IO expander output latch.


Sets the IO expander output latch to VAL. SETS THE IO EXPANDER OUTPUT LATCH TO VAL
10 IOSET 3,16

12. Using the File System

 Minecraft Basic includes a mini disk file system that allows you to load save, and backup programs to multiple disks.

Formatting the Disk

Before being able to load/save programs to disk you need to format it. After loading BASIC load a different floppy into the drive and type DISKFORMAT “NAME” to format it. Everything on the disk will be erased. After the formatting is complete the disk will be ready to use.

Saving/Loading Programs

To save a program, insert a MCFS formatted disk into the drive and type SAVE “NAMEOFPROGRAM”. To load programs type LOAD “NAMEOFPROGRAM”. Use the DIR command to see the exisiting files on the current disk in drive. To delete a program file type DELETE “NAMEOFPROGRAM”.

Making a Bootable Basic Disk

To make a extra disk that boots into Basic, format a spare floppy, then type SAVEBASIC “BASIC”. The boot flag also needs to be set for the disk to boot into BASIC. Type SETBOOT “BASIC” to set the boot flag.

Using MCFSTool to Manage/Share/Backup Programs

MCFSTool is a command line tool used to operate img files formatted with Minecraft BASIC. With this tool you can extract Basic programs written within minecraft to share with others, or move them between multiple img files. Precompiled Windows and Mac binaries can be downloaded at the resources section. Use the readme.txt on how to use it, or ask for help at the forums.

GUI Frontend for MCFSTool now avaliable: Download (XP,Win7)

13. Programming Examples

Door Password Program:

Bresenham’s Circle (Very fast circle drawing algorithm)

Slot Machine


14. Useful Tricks

PRINT INT(RND(1)*(25-1)+1)

Executing Custom Machine Code:

You can either preload machine code into the basic.img file with a hex editor and add 0×500 to get the start address, or poke it in manually within basic. There are two ways you can execute machine code from within basic:

1. SYS(Addr)

E.g. SYS(1024)
This will execute machine code at 0×400 (1024 in decimal). Make sure the code ends with an RTS to be able to jump back into basic.

2. USR

USR is still supported, but we recommend you use SYS instead. To use USR find out where your subroutine is in memory, then the start addresses of the user subroutine is poked into addresses 0xD (low bit, decimal 13) and 0xE (high bit, decimal 14). The subroutine must end with an RTS and stack should be the same level on exit when the routine was entered.

The subroutine I created starts at 0x24C0. The address is poked in little endian format.
0xCO = 192, 0×24 = 36

10 POKE 13, 192
20 POKE 14, 36
25 REM Execute the subroutine
30 X=USR(X)

Peek & Poke

PEEK(ADDRESS) : get value at memory address
e.g. PRINT PEEK(900)

POKE Address, value : insert value into memory address
e.g. POKE 900, 48

Disable Ctrl – C with POKE 2,255

10 POKE 2,255 : REM Unbreakable infinite loop
30 GOTO 20

Disable CTRL-C with POKE2,255. Re-enable it with POKE2,0

108 thoughts on “Basic

    • Thank you, now it’s working i must have been typing something wrong. now i’m trying something like

      10 DEF FN X()
      30 END DEF
      40 FN X()

      I get “?Syntax error in 10″ i’m doing something wrong?

      • Yes, you doing it wrong. :)

        Here’s a detailed description for the DEF command (and for the rest of the basic commands too with examples) *******

        You can not define functions in BASIC. If you want you can use subroutines (“functions” in BASIC) with GOSUB and RETURN like this:

        10 FOR I=0 TO 19
        20 GOSUB 100 : REM SUBROUTINE AT LINE 100
        30 NEXT
        100 PRINT “HELLO WORLD”
        110 RETURN

        And here’s an example of this: *******

        Hope that it was helpful for you, however i am not sure what do you want to do.


      • DEF only supports single line arguments in this version of BASIC, I just tried it out using OSI BASIC and it gave me the same error.

      • Although, one of the things I still seem to have an issue is with the IOSET doesn’t work in a FOR loop if I also use TICKS.. Quite strange?
        It doesn’t cause an error, it just doesn’t actually set the value on the IO Extender

        • Can you show an example? Screenshot of your program or something? It’s hard to say anything without that.

            • That’s because you set it to 0 immeidately. Put ticks between IOSET 3,A and IOSET 3,0 not after :)

              I tested it in emulator and Minecraft too and it’s working well for me.

              • I still think there is a bug, if you take the TICKS out it will pulse very quickly. and that’s with the TICKS command after the IOSETs, before the NEXT

                  • Ah i see. My problem was that I was that the characters were being picked up twice. I guess calling IOGET twice slows it down enough on the other computer.

                    Thanks for your help!

                    • You should implement better handshaking between the 2 computers. Use one of the lines as a RTS (ready to send) and another as a CTS (Clear to Send) from the 2nd computer. The 1st computer waits in a loop until it sees the CTS signal. It then sets the data on the bus, then sets the RTS line and waits for the CTS to go low. It then clears the RTS line and waits for the CTS line again. The 2nd computer Sets CTS high then loops waiting to see RTS high. It then reads the data from the bus and then sets CTS low and waits for RTS to go low, then sets CTS high….I think…I’ve just written that quickly in a tiny text box and can’t check what I’ve written, but it should be enough to point to what is needed. Read up on RS232 handshaking protocols which use something like this in one of the many ways of handshaking it supports.

      • And i made a mistake, so if you downloaded it before download it again please. (Just one people downloaded it, i hope that you know who you are :) )

  1. 100 GET A$
    110 IF A$ = “Q” THEN END
    120 GOTO 100

    Results in Syntax-Error in 110


    90 B$ = “Q”
    100 GET A$
    110 IF A$ = B$ THEN END
    120 GOTO 100

    runs without Error

  2. There is an error with the section above here. should change PEEK reference to Poke.

    Disable Ctrl – C with PEEK 2,255

    10 POKE 2,255 : REM Unbreakable infinite loop
    30 GOTO 20

    Also a question for Bigfoot, is it possible for you to make it so we can stretch the Emulator?, at 1920×1080 desktop resolution I have a hard time reading from that tiny box.

    • thanks , fixed that part of the manual

      The source is available for the emulator, feel free to modify the code to fit your needs.

  3. i installed everything correctly but when i start the PC with 1 8K stuff. when i boot it it says 0 Bytes free. and at every command it says ?SYNTAX ERROR
    and when booting it is not saying 120530b but 120530. so as you might have guessed its very frustrating
    BTW: i tried it with 7 8K stuffs

    • Hey, check if you are using the latest version of Redpower2 (5b2), that might be the problem. (It won’t work on 5b1)

    • Looks like you have the same problem as the guy in the forum. Here’s an answer from someone else for his problem: “Hey, check if you are using the latest version of Redpower2 (5b2), that might be the problem. (It won’t work on 5b1)”

  4. I’ve tried to make bootable disk, but when I set boot flag for my basic program, it stuck when loading in continuous loop Loading MCFS Boot code/Ok. Of course I’ve saved BASIC interpreter by saying SAVEBASIC “BASIC”

    • You can not autostart BASIC programs yet because it needs the BASIC interpreter too… I know, it’s a bit confusing at the moment, i have discussed this problem already with a few people. SETBOOT is much more a MCFS related command than BASIC one. Currently the only “useable” option to use SETBOOT is to set the BASIC file as booting one after a freshly formatted disk with saved interpreter. The boot code doesn’t know that the file which is loaded is working one or not… Standalone BASIC programs (without interpreter) can not run alone.

      I think i will solve this problem with “autostarting” basic programs from the interpreter. Probably searching for a predefined (e.g. “AUTOSTART”) file on the disk then load and execute it after the interpreter loaded and started.

  5. MCFSTOOLGUI seems to have trouble with directories which have a space in them, it throws an error when trying to open an image file in one.

    err.fopen [C:\my]

    the directory they are located in is C:\My Stuff\6502Emu

  6. I would just like to say a massive thanks for this,no nocking Eloraams effort on the mod,but some of the forth commands just dont seem to work in a consistent manner,even the the forget command seems unable to find a newly defined word so how the programs ment to run it i dont know,but this,its like a step back to my old spectrum days,thanks.
    Only thing i would like to see is a way to write my code in a different editor like not pad and still be able to load it.,but i can wait for that.Thanks

  7. Hi,
    super tutorial and there is 1 little Problem…
    MCFSTool don’t work’s right. Error:”err: non mcfs disk”

    My Question: where is the problem? ;(


    • MCFSTool doesn’t have the final boot code yet (neither the format command), so i uploaded an empty mcfs image for download. (I made it with the diskformat command)

  8. Could someone help me with reading individual bits from IOGET()? My best guess is that I if I want the state of bit #X, I need to take MOD(2^X, IOGET(3)) >= 2^X, but the MOD function doesn’t work properly (or it just doesn’t exist. I don’t remember which) and it looks like the exponent function doesn’t work properly. For example, 2^10 is 980.687 when it should be 1024.

    I’ve already managed to make my own exponent and modulo subscripts, but my code is becoming spaghetti by the second. Any chance that you might hard-code a MOD function and/or fix exponents?

    • I fixed the multiplication bug in the v1.0.120616 release.
      The MOD function doesn’t exists, you can use IOGET(3) AND 2^X = 2^X instead, however it will not work correctly on bit 15 (overflow error because of the signed short).
      Slower but always working solution is this: INT(IOGET(3)/INT(2^X)) AND 1 = 1

      In the newly developed version this will be not a problem anymore because the 32-bit integer variables and library.

  9. you can change your disk drive (default = 2) by using
    POKE 7,ID
    where ID is the id of the new drive

    i havn’t figured yet how to write stuff on floppys yet, so it’s basicly an aditional space for programms so far :-(

  10. I seem to have run into an interesting problem. None of my INPUT VAR$ statements are working. All my variables end up with the value of 0. Am I doing something wrong, or is there a bug?

  11. Ok so I’m trying out the Door password Example, but at line 70 it throws a Syntax Error. Apparently Ticks is not working for me.

    • just re-enter the line you want to change as if you were writing it in originally. It’ll overwrite the existing line of code.

  12. MCFSTool don’t works : the GUI dosn’t react to the “write” button, and the .exe just crashes immediatly.

    I’m on Windows 7 64 bits, tried all compatibility mods and admin mod.
    BASIC is correctly installed on minecraft, and .imgs are compatible…

    Help please !

  13. Wow. Brings back those C64 days.
    Now I just need to find something that can run C, lua, or some other slightly more structured programming language on redpower computers. I do like computercraft (despite lua, and despite poor documentation), but I find that it is seriously laggy.

  14. how would i get it to read a input then convert that char by char to ascii
    i know im going to be useing for ,next and asc

    • Yeah, it would be great :D
      I really hope that you make a AutoStart program, that launches when the terminal finishes booting :D

  15. When I try and start it it says 0 bytes free even though I put an 8k ram module on the back and whenever I put in a command I just get “?SYNTAX ERROR”.

  16. Hi,

    short question, is there a away to prevent a programm form ending after an empty INPUT like 10 INPUT A$ (press enter without any string writen)
    20 ….


  17. I tried conneting 2 CPUs, 2 Consoles, 1 IO and one disk drive to one buc but couldn’t make the cpus talk to their appropriate console. To be precise: Both were always talking to the same standard-ID console. Same setup works well with standard OS. Seems like you are not reading the target id for the console, but rather use a default value.

    Keep up the good work! o7

  18. I run a small server using Tekkit. Is there a way to take the rpcboot.bin and replace the default “Forth” with the MS-BASIC on my Tekkit server? I have found the redpower archive in server side tekkit folder. If I were to delete the existing rpcboot.bin file (from withing the .zip) and replace with the MS-BASIC version, will it simply boot up as MS-BASIC instead of Forth?

  19. I got it working. I opened the redpower archive, deletec the .bin file, delted the redroth.bin. Then I renamed the Basic.IMG to redforth.img, and copied the new .BIN and the renamed BASIC.IMG file into the archive. Reinstalled the archive into the MOD directory and up and running on my Tekkit server using MS-Basic v2.0.120603.

  20. ok i think i found a serious bug. you are able to set lines above 255 within mc and youre able to save them to a floppy and even run those without problems. but if you try to detokenize those it suddenly stops around ~250. interesting to note is that the extracted tokenfile still contains all information (as far as i can tell those cryptic tokens and my strings)

  21. !!!! This is Epic. Reminds me of my days programming the Commdore 64 as a kid. Suddenly, everying in minecraft has gotten easier to control ;)

  22. I’m starting to use basic now, I may be talking nonsense, but I can give a suggestion, create a function to convert numbers to binary and binary to numbers, sometimes just want to know if a thread is active in a value of type 8193, Example IOGET (ID, COLOR).

    • From thre Just Basic forum:

      Function JBDecBin(dec)
      While 1
      bin$ = str$(dec MOD 2) + bin$
      dec = dec / 2
      If dec = 0.5 then
      JBDecBin = val(bin$)
      Exit While
      End If
      dec = int(dec)
      End Function

  23. Hi, First of all Thanks for making RPC/8 to use so easy and then i would like to ask how can i get is there any key down(and which) or in another ways how i can read keyboard buffer which i saw was implemented. Thanks

  24. Does anyone know how to save and load data to a disk and how to read data from the disk? In my case, i want to create a matrix by the user (width, height, matrix(width*height) and save it to a disk. The computer of a frame base build robot should read this matrix from the disk. Is this possible with Basic 1.0?

  25. It seems the io expander isnt working for me, neither on Forth nor with basic.
    I can use to commands and everything else but commands like ioget,ioset just wont work.
    Someone with a similar problem?

    • Make sure the cables are connected to the correct side of the module. That was my original problem. Other than that the IOGET , works jsut fine.

  26. Love what you did… FORTH is kind of unreadable for me but basic is what I started programming with, on my 48k spectrum :D .

    Not a complain, but just in case you are fishing for ideas:
    Would be nice to have some sort of include so routines used by multiple programs could be “simply” included and called using GOSUB.
    The include would merge a program into another one.

    Anyway, very grateful for what you did here.

  27. I posted this on the resources page, but I thought it would pertain to this too:

    Yeah, I love being able to work with BASIC instead of FORTH, but the problem is that when I try to use MCFS (GUI or Command Line) or the Tokenizer, it fails, giving me a “fopen error,” whatever that is. If it helps, I’m running Windows 7 Home Premium x64 v. 6.1 (Build 7601: Service Pack 1), and I tried both the GUI and Command line versions of MCFS, and the command line tokenizer. But really, really big ups to Eloraam for this emulated computer and slightly less big but still very big ups to BiGFoot for the BASIC OS. Perhaps we should call it Mine-BASIC?

  28. Whenever i put in a simple command like SAVE it says unknown token: SAVE

    why does it do this? it does it with all commands like that.


  29. How do i access the rednet protocal with Basic? I would like to set up a password server with basic so i can manage all my door passwords in one location. Is this possible?

    • PEEK and POKE. No other way, sorry. Read up on redbus on the Redpower Control page on the Redpower wiki (just google “Redpower Control”, ought to be the first result).

  30. It seems using boolean operations (that is, 63 AND 16 = 16) on variables is broken.


    PRINT 63 AND 16




    PRINT X AND 16


    Apparently, it doesn’t know what to do with the AND after the variable.

  31. Maybe I found a little Bug…
    When waiting for an Input string
    50 CLRSCR
    51 PRINT “Enter Password: “;
    52 INPUT IN$
    53 IF IN$ = “PASSWORD” THEN GOTO 100
    55 GOTO 50

    It WILL correctly work and compare Password in IF Statements, but on just hitting enter it seems to quit program und just shows “READY”.

    This should’t happen right?

  32. HI! got it installed it appears to boot on the RPC in game displays:”
    “Minecraft MS-BASIC V1.0.120616″
    “0 Bytes Free”

    after that all it will do in say
    “?SYNTAX ERROR” <<<< havent seen this in 35 years! hahaha

    the in-game boot disk works but not the MS basic :(


  33. Hello!
    First off, great job in the basic language for the redpower computers! Totally awesome!
    What i do lack is an editing tool ingame…. its so tideous to write every line all over again when i make a mistake…

  34. Is there any way to change terminal or disk address with Basic? In Forth, it was

    I had a program designed in Forth that switched between two different monitors for a password entry. If this feature isn’t in Basic, could it be added by any chance?

  35. Would be great if you added the pastebin function that the lua console has. Make it so easy to get code in and out of the computer.
