Not realy answering the original question, it's still
a mistery I guess. :-)


I'm generally against "self-submitting" COM files becuse it's
hard to get an overview of all jobs running. And if something
crashes (before the submit command), the job is "lost".

It's is also messy for jobs that runs multiple times during
each 24h period. And as I think Hoff said, the risk of
someone hitting "/release" on a holding job... :-)

I uses a cron-like tool (called CRON :-) ) that I found
many years ago. This way all scheduled job are in one
configuration file and it's simple to get an overview
using one TYPE command.

It also takes care of such things as "not on sundays",
"only the 1'st each month" and so on.

The CRON server itself is a DCL-only COM file.

Example of configuration file:

$ type util:<cron>crontab.dat

# cron example
# command order:
# Field:  1    2    3     4      5
#       hour day month D-O-W  command
#
# CRON matches against first four fields and then
# considers command
#
# First four fields (time) can be any of the following:
#       1) Single number --> must match exactly
#       2) number - number --> match inclusive range
#       3) number,number --> match any in the list
#       4) *  --> wildcard, matches anything
