Most commands are written as functions

[COMMAND_NAME]([OPERAND1],[OPERAND2],[OPERAND3...])

neg(a)	return -a
gt(a,b)	return a > 0
lt(a,b)	return a < 0
eq(a,b)	return a == 0
jump(a)	jump to line a
input(a)	if a = 0 then return num_input else return char_input_as_num
not(a)	return !a
and(a,b)	return a && b
or(a,b)	return a || b
if(a,b,c)	if a then b else c	Can span multiple lines
output(a,b)	output a if b = 0 else output char(a)
let(a,b)	let a = b
define(a,b0,b1,b2...c)	def a(b0,b1,b2...): c	Variable amount of inputs. Must have atleast 3 inputs. Can span multiple lines
halt()	halt	The only built-in function to have no inputs
