Robert,
You could try the following:
!setvar _ExecCount 0
!if SETVAR(_JobCount, JOBCNT('@J:!hpjobname,!hpuser.!hpaccount',
_JobList)) > 1 then
! setvar idx 0
! while SETVAR(idx, idx + 1) <= _JobCount OR _ExecCount < 2 do
! if JINFO("![WORD(_JobList, ,idx)]", "State") = "EXEC" then
! setvar _ExecCount _ExecCount + 1
! endif
! endwhile
!endif
!if _ExecCount > 1 then
! tellop WARNING: Job is already running. I'm terminating.
! eoj
!endif
You may have to change "!hpjobname,!hpuser.!hpaccount" unless ALL these
'copy' jobs do log-on with the same jobcard.
Regards
Paul Christidis
