Ifdefs

[dazappa]

Currently using FPC 2.2.4, and I've found these lovely things called IFDEFs.
Ex:

{$IFDEF FPC}
{$MODE DELPHI}
{$ENDIF}
Is there any way for me to define my own variables for these? I'd like to create an {$IFDEF DEBUG} so that the code won't be compiled and run in the final application, whereas just having a "if(debug) then" everywhere will be compiled and will be executed.

Yes, you can :)
Something like this should do the trick


{$define MyDebug}

{$ifdef MyDebug}
writeln('Debugging...');
{$endif}

That is unless compiler optimizes it out. If your debug variable is constant it just might do that but i'm not sure.

Thanks. The info on that link (+ ifdefs) seem oh-so-helpful. But, currently I really only needed/wanted the ifdefs but I'm sure I'll have a use for the others in the future.
