Conditional compilation based on a compiler directive in Delphi 2009


Is there a way in Delphi 2009 to have a section of code conditionally compiled based on a compiler directive. Specifically, I'd like to have code in place that is only included if the range-check compiler directive is turned on.

Something like this:

{$ifdef RANGECHECKINGISON} [do range checking code here] {$endif}


Solution

  • Use {$ifopt} instead of {$ifdef}:

    {$ifopt R+} // if range checking is active
    ...
    {$endif}
