I wonder what I'm doing wrong (again). I made an assembler program that
I call with Address LINKPGM. It's in the linklist, it's APF authorized,
has the AC bit on, and listed in AUTHPGM in IKJTSO00.
There is an alternative to LINKPGM, but the name escapes me at the
moment. It might be LINKMVS or AUTHMVS (I'd check a PDS member list of
SYS1.LINKLIB)? It's been ten years, but when I worked at an ISV this was
a standard way of handling things, provided all the details were taken
care of. I do remember having to handle different formats for passing
parameters, though.

There are these ways to invoke programs from REXX execs (aside from CALL):
ADDRESS LINK
ADDRESS ATTACH
- passing a string, which may have variables substituted
(if not in quotes)
- received as R1 points to two words in memory
1st word points to a pointer to the string
2nd word points to the length as a fullword binary integer
ADDRESS LINKMVS
ADDRESS ATTCHMVS
- pass multiple parameters as variables (substitution occurs
even though the variables must be quoted)
- received as R1 points to a list of pointers
each pointer points to a half-word prefixed string, one for
each variable passed, of course
the last pointer has its leftmost bit turned on
- the values of these parameters may be changed by the called program
ADDRESS LINKPGM
ADDRESS ATTCHPGM
- pass multiple parameters as a quoted string of variables
- received as R1 points to a list of pointers
each pointer points to its corresponding parameter string
* no length indicator
- values may be changed by called program but, of course, no
value may have its length changed

We cover the above, with examples and labs in Assembler,
COBOL, PL/I, and C in our 2 day course "Introduction to
TSO and REXX APIs" (we don't over authorization issues)
