A keyed DELETE is just another way of saying CHAIN/DELETE.You must "GET" a record to lock it before you can UPDATE or DELETE it, hence there must always be a read to get the lock.
SETLL does not get a record, it simply positions the pointer. So a SETLL followed by a DELETE will result in an error.

Hmmm! Does a keyed DELETE "include" a CHAIN or SETLL, hence the read? Would it behave differently if you SETLL by key and then DELETE without key? Would that work? Been too long!-------------- Original message --------------I would like to confirm something that was just discovered. I have atrigger program (RPGILE) attached to a file that executes only when a read event occurs. But it appears that a 'DELETE' operation on that file causesthe trigger to fire. This is not a situation where I read a record then issue the 'Delete' operation. This is a 'delete' operation where the key is specified. Can anyone confirm this? This particular application has aseries of program calls, that because of the 'read' trigger being executedas a result of a 'delete' operation causes a recursive call. Thanks for any input.
