SLEEp n :

This is a very polite keyword that will take your system administrator off your back. You can use SLEEp to make QS run only for a specified time interval of the day (usually overnight). This you do as follows : suppose that most users go home at about 1900 hours and come back in again at 0830 hours next morning. If you submit your job using the unix command at 2000 and you give SLEEP 12 in your input file, QS will run for 24 - n = 12 hours (from 8:00 in the evening until 8:00 next morning) and then will go to sleep for n = 12 hours (till 20:00 in the evening). Note that the time at which the job is started defines QS's sense of time (so it is critical that the job gets started at the right time). VMS users must use the command line option /AFTER=... in their submit command (but have a look at the help page on submit/after because there are some timing peculiarities with VAX clusters).
