Thanks to all who responded especially Bernd and Timothy. I have forwarded a summary of the replies to the customer, and will be encouraging them to upgrade to Enterprise PL/1 and supporting them in their work. FWIW this is not a dead or dying system, they have invested heavily in PL/1 over the last 30 years and have 50+ production CICS regions running PL/1 with interfaces to MQ, and code is still being written. (The mainframe was supposed to be gone in 2008, but hey .... ) I think it's the misapprehension that a mass recompile was compulsory that has stopped them upgrading before now. Anyway thanks again

The platform seems already to be almost dead there (if not PL/1 is only, say, 5 % of the inventory, and the rest is, for example, COBOL ... then staying with such old releases could well be a matter of economics ... I would not act this way, if I had to decide, but often such decisions are not made by tech people. BTW, at the site where I am working, we are staying with EP PL/1 3.9 for similar reasons since three or more years now, I think).
