BFasm

Simple language that compiles to brainfuck.

• Memory is not used in a tape, but there are variables.
• Variables are a single cell, unless written as var[number], in which case multiple ones are reserved.
• Variables are defined at the start of the program.
• Note: they might not be in the same order as defined at the start, and/or they might have data inbetween.
• Comments are defined as // until end of line.
• Every operation is on its own line.
• Operations are case-insensitive. Variable names are case-sensitive.

Supported operations

WHILE   var
IF 	var
UNTIL   var
END

SET     var      val
CPY     srcvar   destvar
ADD     var      (var/val)
SUB     var      (var/val)
MUL	var	 (var/val)
DIV	var	 (var/val)

//both implemented by means of a simple . or ,
READ    var      (number of chars to read)
PRINT   var      (number of chars to print)

//assumes terminates with memory in the same position and that it doesnt mess with code outside the var.

Variable definition

At the start of the program variables are defined as follows:

varname
arrname[arrsize]

Variable/program are seperated by a line that contains nothing but !.

Input methods

val

• Decimal numbers: 215
• Hexadecimal numbers: 0x36
• Chars/strings (' and " are equivalent): 'string' "c"

var

• Variable: varname
• Array: arrname[val]

Example program

helloworld[12]
!
SET helloworld "Hello World!"
PRINT helloworld 12
