I will also look for an "exit point" on opening the file, maybe I
can limit the open to only read.
No reason to "look for". That is the Database Open exit. But as
with ALWDLT(*NO), the Database Open exit will not enable preventing
Clear because that method is not implemented using Data Management Open;
a delete trigger will still be desirable even if the exit prevents all
but read-only opens.

The Open Database File exit program is called when a job is opening a
database file. This exit is called in the job that is attempting to open
the file. The exit program is passed a list of files referenced in the
open request and the open options. The exit program may set a return
code value to end the open request. When an open request is issued, the
operating system calls the user-written exit program through the
registration facility. For information about adding an exit program to
an exit point, see the Registration Facility APIs.
