Debugging with conditional compiler directive

Problem/Question/Abstract:

How to use compiler directive {$IFOPT switch} for debugging ?

Answer:

The usual way of using the compiler directive is to first define using {$define debug} and use $IFDEF and $ENDIF

The method given below is similar with an additional advantage.

For example you can use the following code for debugging with GExperts

{$IFOPT D+}, DbugIntf{$ENDIF} //in the uses

{$IFOPT D+}
SendDebug('Data=' + InttoStr(TestVAlue));
  //whenever you require to display to the GExperts debug window
{$ENDIF}

The advantage of using $IFOPT D+ is that, the debug statements are automatically removed once you remove the debug info in the project option properties(Project Options->Compiler ->Debugging) .
