RE: Read Trigger

After it's read, but before it's returned to the calling program.

R Bruce,

>first, it can only be an *after read
>third, allow repeated change yes is permitted

Isn't this a contradiction in terms?

As I recall, the real problem with *READ triggers is that you can't use
ALWREPCHG, since you can't use *BEFORE, and thus you can't blank out selected
fields.  Or even issue the escape message until *after* it is already read.

I've never understood the logic in that limitation.
