Is there any reason you suggest LINKPGM rather than LINKMVS?
LINKMVS sets up all the parameter(s) GIMSMP can use, with less
computation of length fields, etc.  (I recognize that for some
functions, such as ICSF, only LINKPGM can set up the needed
parameter formats.)

If I did "address LINKPGM IKJEFTSR ...", wouldn't REXX (via LINKPGM
or LINKMVS) not cause IKJEFTSR to run APF authorized, and GIMSMP and
then IEBCOPY would in turn (try to) operate unauthorized?

I looked up IKJEFTSR for the first time.  You likely suspect I like
playing around, but not as much as that.
