define questions

[webmasterpdx]

You defined INC2 as X+2. That would mean I'd have to use it as in n:=INC2(n);
I see what you are saying....n is local to INC2, so I'd have to use it this way. I wanted to be able to increment a variable without having to type the variable twice, as in x:=x+1;
....kind of like ++x; in C.
I might as well type in n:=n+2 rather than n:=INC2(n);
I can create a regular program to do it. It would have been nice to define a function though (more elegant), where I can whip out quickly common functions that I use a lot. I've had a thought though, (possibly using 'n' as an argument, which "kind" of works like passing in a pointer)....need to experiment a little. I'll post if I can get it to work.
Thx
