Programming Language Design Help

Hello,

I am writing a programming language in c++ for a class and I am having a problem understanding how to do some of it. The language is based on Forth, and you are allowed to redefine how any of the words in the language work. I am trying to understand how to store the instructions for each of the words. If anyone can shed some light on some methods of accomplishing this, it would be greatly appreciated!

Thanks,

Nick

Re: Programming Language Design Help

It depends.

What features of the stack language are there? What values could possible appear on the stack? Numbers? Integers, Doubles? Strings, arrays, linked lists? Do you want to have runtime checks to see what kind of data structure you're dealing with? Can pointers (to functions) go on the stack? Do you want to be able to construct functions in the middle of code?

I guess it is a compiler project assignment, you can probrably use lex and yacc to do it.
