RCX NQC variable types

What different types of variables are available in NQC? I know "int" is, but that seems to be the only one. Is it?

The RCX firmware supports only one variable type so NQC only gives you one type. 16 bit signed integers using the "int" keyword. You do have access also to arrays of int and int pointers if you use the RCX 2.0 firmware and the latest NQC compiler.

Ok, that is what I suspected. Thanks. What are int pointers?

Int pointers are pointers to ints

Basically, instead of a memory location holding a value like "100", it holds the value of a memory location of another variable. Everything you wanted to know about pointers but were afraid to ask: http://pw1.netcom.com/~tjensen/ptr/pointers.htm

Ok, I think I understand now. Thanks.

Pointers are an awesome way of messing up your program in fantastic and unpredictable ways that are almost impossible to debug.

LOL. I can see that in theory, that could be very true.
