Sorth

Sorth is an interpreted, stack based, typeless language implemented from a stackoverflow answer, alongside some extra features
Current status: Released!

Syntax

The language has a stack and 8 instructions:
push <num> push a number on to the stack
pop pop off the first number on the stack
add pop off the top 2 items on the stack and push their sum on to the stack.
ifeq <lineno> examine the top of the stack, if it's 0, continue, else, jump to line number
jump <lineno> jump to a line number
print print the value at the top of the stack
printa print the ascii equivalent of the value at the top of the stack
dup push a copy of what's at the top of the stack back onto the stack

Comments can be added by prepending the comment with the # symbol.
Comments, however, cannot be beside a instruction.
