Logic syntax

[Randy]

Is it possible to string three or more items in an "if" statement that use the "&&" ?

I get errors when I do something like this:
 if (v101==1 && v102==1 && v103==1) {

whereas if I did the same thing with "||" it worked
 if (v101==1 || v102==1 || v103==1) {


However, I need the results of using the "&&" so I resorted to a solution like this:
 if (v101==1 && v102==1) {
   if (v103==1) {
     //code
   }
 }


Is this a severe limitation of AGI or am I miscoding something?

If my understanding of the AGI Specs is correct (and it better be, since I'm coding something that generates compiled code), then it should be perfectly legal to say:

if (v100 == 2 && v101 == 3 && v102 == 4)

In fact, I just tested that very if-statement in AGI Studio (v.1.35) and it compiled without complaints. I assume that's what you mean when you say you get errors -- compile errors? If that's the case, then the error must be a different problem.

yup, compile errors. It would not let me compile, yet it would let me compile the identical "or" statement. I don't have the computer I used for this project in front of me so I can't tell you the exact error message, I can check that out tonight though.

Hmm... weird.

make sure that you didn't type something to the effect of

if (v1 == 1 && v2 == 2 && v3 = 3)

because that is a syntax error. You can't have v3 = 3 inside an if-statement in AGI (although you can in C) -- the compiler will say "expression syntax error" or something like that. Aside from that, I can't tell you more with what I know right now. The code you're trying to write compiles even in AGI Studio 1.31 (Peter Kelly's last release).

check your spaces and make sure none are tabs.. the compiler might not like them.  The error msg would be helpful though.
