One of the compilation options is to stop compilation and leave the
cursor on the source at a particular code address.  I believe this
option exists for TPascal 3.0 and am certain it exists in 4.0 and
later.  Since you mention the debugger I'm assuming you have 5.0.
Poke around in the compilation options menu and you should find it.

The kind of error which you're experiencing I try to trap using the
$i- compilation directive; compile your program with that and check
ioresult after any command that could fail (the manual lists them
somewhere, in addition to some source fragments showing how to use
ioresult).  Your program can then warn you any way you like and you
won't have to worry about it again.
