Why not define?
{$IFDEF DEBUG} Writeln('diagnostic info'); {$ENDIF}

I have a whole section of diagnostic writeln's in a program, and it's tedious to comment them all out/in as needed.   I'm curious if doing something like
 If diagnosticdetail then Writeln('diagnostic info');
 Is the same as 
 // Writeln('diagnostic info');
 And the Writeln will actually end up being left out of the compiled program altogether... since the constant will never allow it to run,  or if not, is there a better way to optionally exclude diagnostic information entirely from the compiled program?
