R – Conditional compilation based on a compiler directive in Delphi 2009

compiler-constructionconditionaldelphidelphi-2009directive

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}

Best Answer

Use {$ifopt} instead of {$ifdef}:

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