When I worked for IBM I saw how protective IBM was of the PL/S, PL/AS, PL/X compiler. All of the manuals were marked IBM Confidential. There were security audit police that would check a particular MVS system where the compiler was installed to make sure it was installed according to corporate instructions. I think it had to reside in its own linklist load library and the compiler was marked with a RACF attribute of "execute only", meaning that the OS could read the load module from disk for the purpose of executing it but a user couldn't make a copy of the load module. I don't remember for sure but it might have been the case that anyone who wanted to use the compiler had to be a member of a particular RACF group.
I understad, really an hyper protective behaviour.
Just because MVS had been rewritten in this language?
By the way, from what I've seen, MVS3.8j sources
are pure assembler, with some PL/S source stored
as comments, but it looks to my eyes as a pure
assembler OS.
When MVS had been rewritten in PL/S?
