Mike,
For security reasons, REXX Programs can’t normally call an APF Authorized
program (it causes it to loose its APF Authorization). There is one exception,
from SystemREXX. You would be able to create a SystemREXX that uses LINKMVS/PGM
or ATTACHMVS/PGM to call the program and then use
Looking for some advice on the simplest way to call an authorized assembler
program from a non-compiled Rexx program under TSO/E in batch, with the
requirement that multiple updatable parameters will be passed. Updating

If A and B are marked serially reusable, A sometimes does a LINK to B and B
sometimes does a LINK to A then a deadlock is likely.

Serial reusable: a task can load the module, call it, then call it again and
get correct results. The OS will seralize LINK to the module from different
tasks.

correct results. The code is responsible for any

Reentrant means that it works correctly when multiple tasks are using it
concurrently. Refreshable means that it works correctly even if the OS replaces
it with a clean copy.
As an example of a routine that is reentrant but not refreshable, consider a
routine that contains a data area and

Very simple: reentrant module is allowed to modify itself, provided it
uses locking to serialize execution by multiple tasks using that module.
Very common technique in system code. Refreshable cannot do that as it
could be refreshed at any time (which would change the locked/serialized

Right, and if it's marked that way then there should be no issue if there is a
separate LINK or LOAD for each use, or at least if there is an issue I don't
understand what it is.

The OP did say that the assembler module is *known* to be not reusable
i.e. each call needs a new copy.
Speculation about *maybe* it's not reusable and whether that was
intended
Ok.. so I am not sure I ever asked this question... What is the real
difference between reentrant and refreshable .. as in an example? It is
not clear what the distinction actually is.

If you init fields that are updated it should work as serially reusable.
If you work with getmain storage then it would be reentrant.
If results are dependent on the value in the load module and it gets
changed, you have to reload each time.

IBM documents this crisply at

Bottom line is that there are only 3 variants: serially reusable,
reentrant and refreshable.
Non-serially reusable is reentrant, but that term isn't used in Binder or

After doing that, I still received the error. However, in the

My recommendation is to use SDSF or ISRDDN for this functionality as they are
supported products.
MXI 4.3 has not been maintained for nearly 20 years. It is unsupported and to
be brutally honest showing its age a bit.
(The fact that MXI 4.3 is still functional at all is a testament to
IT's MXI!

Maybe I'm mis-using the term "reusable". I'm not referring to "serially

while it still known to be in use). I'm referring to simply using it once and
then using it again.

Sry it's a copy paste error. It should read as I instead of 1.
