A tip for the next time you have problems with macros: use Xcode’s Preprocess
command (in the Build menu) to see your macros resolved. Helps a lot in such
cases.

I don't mean to play teacher's-pet, but the moderator did just post the list
guidelines a few days ago, including "no plain C questions". There are better
places to ask those, including stackoverflow.com.
Also, a tip: If you ever have weird errors involving #defines, Xcode's
"Preprocess" comman
Thanks! I can't believe I missed that. Its 1:35am here and its been a long day.

Leave out the semi-colon. #define is a macro, the complete text is simply
substituted for the name before compilation even starts, so you have the
equivalent of if(NO;){...} which is invalid syntax.
.. oh and
static BOOL IsDemo = NO;
is a better idea anyway I think ..

Take the ';' off the end of the #define, the replaced text is everything to the
end of the line, remember #define is just a text expansion, so with this
#define IsDemo NO;
replaced in this
if( IsDemo ) {
you're doing this
if( NO; ) {
and that's your syntax error

#define's are basically a simple find and replace, so if you do:
#define IsDemo NO;
and then do:
if (IsDemo) { ... }
It's going to become:
if (NO;) { ... }
See the problem? You've got a semicolon in there. Generally, you don't end a
#define with a semicolon unless you want a semicolon in t
I have the following constant set up. I have tried all three of these
variations and none of them work in an if statement in cocoa. I get
error: expected `)' before ';' token
#define IsDemo NO;
#define IsDemo false;
#define IsDemo 0;
if (IsDemo) {
bla...
}
Same problem, when I try:
#define Fr
