compile date

I have a small, rather trivial, question. How do I access the compile date (and/or time) of a program so I can display it to the used when asked. e.g. I would like to write... writeln('Compile on:',__DATE__, __TIME__); { borrowing from c } or put it up in my MacOSX GUI 'About' box... SetDialogItemText(theItem, {$I %DATE%}); { Free Pascal way to add compile date } Is there a way to do this with GPC? Regards, Steven
