is it possible via {$define xx} to define an constant value (like CompilerVersion)-CodePudding

is it possible via {$define xx} to define an constant value (like CompilerVersion). For example I would like to do something like

{$define FrogCount=25}

but seam to not work :(

I need to do this inside a myincfile.inc file because I need to do stuff like

interface

   {$I myincfile.inc}

uses
  {$IF FrogCount = 25}
  toto;
  {$else}
  lala;
  {$endif}

and you understand that here I can't do stuff like

const FrogCount = 25;

inside myincfile.inc else I have a compiler error :(

CodePudding user response：

In Delphi, you cannot define a constant value in a {$DEFINE ident} statement, you can define only the ident name by itself, which is then usable only with {$IF(N)DEF ident} and {$IF (NOT) DEFINED(ident)} statements.

In FreePascal, you can define a constant value in a {$DEFINE ident:=expr} statement, but only when {$MACRO ON} is enabled. See Macros in FreePascal's documentation.
