This is neither a C problem nor a Pascal problem but a problem of
interfacing DOS.

EXEC is a wrapper for the DOS EXEC function which executes the program
_instead_ of COMMAND.COM. Redirection is a service of the command
processor. EXEC expects the parameters to the program and not the
parameters to COMMAND.COM. You would have to call the program via the
command processor.


   exec(getenv('COMSPEC'), '/c c:\g32\bin\ls.exe -l y > log');
