Shaun:
Remember, when you start going down the "trigger" path in UD, you may
want to simply create two globally cataloged routines:
U2.MASTER.TRIGGER.D
U2.MASTER.TRIGGER.U
...or something like this. These two triggers simply "call" defined
subroutines. We use a TRIGGER.CONF file like:
001 FileName@VMFileName@VMFileName...
002 UpdSubroutine@SVMUpdSubroutine@VMUpdSubroutine@VMUpdSubroutine...
003 DelSubroutine@SVMDelSubroutine@VMDelSubroutine@VMDelSubroutine...
...where field# 2 is used by the "update" trigger and field# 3 is used
by the "delete" trigger. With a structure like this you'll be able to
insert and remove subroutines into triggers (after you create the
trigger), and use "local" subroutines. Plus none of the trigger
programs, except the two master trigger programs, will need to be
globally cataloged.
HTH,
Bill

*Subject:* [U2] UniData Triggers
We are creating a trigger on a file that is used extensively in the
system. Is it necessary to logoff users when creating an update trigger
on a file or does UniData handle that when updating
the trigger information to the header of the file? The 'help' does not
specify whether trigger creation requires exclusive access to the file
or not.
Thanks!
