Built-in Instructions
Here is the list of all built-in instructions.
| Name | Arguments | Function |
|---|---|---|
| ZERO | addr | sets the value ofaddr to 0 |
| INCR | addr, value | increments the value of theaddr cell by value |
| DECR | addr, value | decrements the value of theaddr cell by value |
| ADDP | addr1, addr2 | addsaddr2 to addr1, the result is stored in addr1 (in place) |
| SUBP | addr1, addr2 | subtractaddr2 from addr1, the result is stored in addr1 (in place) |
| COPY | addr1, addr2, addr3 | copies the value ofaddr1 into addr2 and addr3 |
| WHNE | addr, value, [scope] | while the value ofaddr cell is not equal to value runs the [scope]. addr is not consumed |
| IN | addr | takes input from the user and sets it inaddr, behaviour will vary between bf implementations |
| OUT | addr | outputs the value ofaddr, addr is not consumed |
| LSTR | start_addr, "str" | loads the string character by character into cells from thestart_addr advancing forward |
| PSTR | addr, "str" | prints the string character by character using the celladdr as a buffer |
| ALIS | ident, value or [scope] | creates an alias to a value or scope namedident. This instruction is purely abstraction |
| INLN | [scope] | inlines a scope |
| RAW | "str" | includes the string after transpilation, this can be used to include brainfuck operators |
| BBOX | addr | moves the tape pointer toaddr |
| ASUM | addr | tells to compiler to assume that the tape pointer is ataddr. If that assumption is wrong all cells accesses will be offset |
