$D
Compiler Directive
Determines whether application debug information is built
1   {$D-}
2   {$D+}
Description
The $D compiler directive determines whether Delphi builds debug information for the application.
 
By default, Delphi builds the information, which provides the line number when a program abnormally terminates.
 
The overheads for keeping $D on are minimal.
Notes
$DebugInfo is equivalent to $D.

The default value is $D+
