You want to assume E coded on all operations in the program?
Yikes!  That means you would have to code IF %ERROR after
every statement to ensure that you can handle any unexpected
exception that crops up.

I guess I don't understand what you're asking for here.

The *PSSR and INFSR give you two programming problems:
1) Figuring out where you came from; and 2) determining
where to go next.  These two problems are basically
equivalent.

Having a *NEXT (or *CONTINUE) option on the ENDSR helps
on the 2nd problem, but you still need to know where
you came from any time there is the possibility of
exceptions occurring in more than one place in the program.
