this is my solution:

1. for example , i have a idl runable program that is named ama, the path is /usr/local/itt/ama/

2. i create a file that is named cron.ama under /etc/

3. $ vi /etc/cron.ama,
# run ama at 12:30 everyday
30 12 * * * cd /usr/local/itt/ama/;./ama

4. $ crontab /etc/cron.ama

5. this all, you can use ps -ef to find the ama process at 12:30 , and work nomally until you kill it.

ps : $ crontab -e edit crontab
$ crontab -r rm cron which you add

Good Luck!
