Terry,


Does your program require environment variables to be set before running the program itself?

By default cron does not create an user environment.

To set an user environment I use a script,say cron-pascal-program.sh with a content like:

su - user -c /path/your-FreePascal-program


and the cron entry like:

0 0 * * * /path-to/cron-pascal-program.sh


Other option, I have not tested: cron entry

0 0 * * * /bin/su - user -c /path/your-FreePascal-program

This way your user environment is set at runtime of the Pascal program.
