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.
