I'm coming, slowly but surely, to Object Pascal…
I used to use {$MODE MACPAS}
but for ObjectPascal, I must use {$MODE OBJFPC}
And so : in MACPAS there was a very very very usefull directive : {$SETC bidule := TRUE}
which was invoqued later by {$IFC bidule} … {$ENDC}
is there any way to have the equivalent under OBJFPC ?
