Cannot open file 'sql.iem'

I'm having a wonderful time implementing a script which runs out of my crontab. Here's the sacego command that bombed: IFXDIR=/informix/bin ASPIFX=/ASP/bin/Informix $IFXDIR/sacego $ASPIFX/get_units Here's the error message: Cannot open file 'sql.iem' Here's my question: What is 'sql.iem'? I won't bog down the network with the get_units.ace source since it runs fine in foreground. Judy
