[fpc-devel] Compiler bug in macro handling?

[Bernd Oppolzer]

Hi Guiliano,

I'm no FPC macro language wizard, but in my believe
you are replacing Positiva with False, followed by a semicolon,
and so you get the error from the compiler.

{$define Positiva:=False}

should probably work.

HTH,
kind regards

Bernd
