   What you should do depends on what you want to happen.  Around here,
I have a DAILY.COM.  It does many things, but the last thing it does is
re-sumbit itself:

$!
$! Re-submit the latest version of this procedure.
$!
$ CPR = F$ENVIRONMENT( "PROCEDURE")
$ CPR = F$PARSE( ";", CPR)
$!
$ IF (CPR .NES. "")
$ THEN
$    SUBMIT  -
      /AFTER = "TOMORROW+ 00:10:00"  -
      /NOPRINTER  -
      'CPR'
$ ENDIF
$!


   Thus, it gets run every day at 00:10:00.  (The 'F$PARSE( ";", CPR)'
thing makes sure that it uses the highest version of the file if you
edit it, instead of the same version as before.)
