Maybe I'm totally wrong, but the reason for this suggestion

"you should IMO not require a current release"

is, that I have the feeling that there are some people out there that still use
old compilers on platforms that I am not familiar with - today - for example, VM
and VSE.

I am in the z/OS business exclusively since almost 15 years now, and we had the
current z/OS PL/1 compilers most of the time - only recently, we are a bit
behind schedule (3.9 - the current release is 4.4).

I have the impression that it's not a good idea for a public domain software to
require the latest release of PL/1.

@D.: as I understand your post, you will support older compilers, but the
newer compiler will be required for the PL/1 glue code ... and that would not be
necessary with the C glue code solution.

Kind regards

Bernd
