Re: RPGLE with embeded SQL cursor over file with *READ trigger

they are "in use" (e.g. called or activated in some jobs).

However as I recall, the OS, specifically the database component of the OS, *does* lock a "trigger" program when a database file, one which previously was associated with that program as a trigger [ADDPFTRG; or CREATE TRIGGER, but there is no *READ for SQL triggers], is opened for the type of I\O covered by that trigger.
