Hi!
I've a big problem. I wan't to write a getpixel routine for my own BASIC
interpreter GBasic, using BISON. The problem is, i don't know how to
define a BISON function that returns a value.
The Syntax should be like:
a = getpixel 100, 100
I tried
| GETPIXEL expression',' expression,
that won't work, just like
| expression '=' GETPIXEL expression',' expression.
Can somebody please help me?
