Program Document question

I’m trying to setup a program document that runs the following command at 5:00 am every morning. Tell MTC purge 14. So far no matter whatever I place in the document it doesn’t work. It either ignores the command all together or gives me a message that the particular EXE file doesn’t exist. Does anyone know the exact synatx I need to place in my program line and command line?

Thanks,

Gail
