Can anyone tell me what (some of) the main differences are between these two? I've found links to the Kednos manuals, but they date to 2003, and that would make them seem rather dated?

Did anyone ever reply? Kednos PL/I is DEC's compiler from the book
"Engineering a Compiler." It is, I believe a complete Subset-G compiler,
but unfortunately is for VMS/VAX and VMS/Alpha only, with no intention
to port it anywhere else.

IBM Enterprise PL/I is full ANSI PL/I with a bunch of extensions. (I
think) it runs only on IBM z/OS and z/VM. At one point there was a
windows version, but I don't think it's supported any more.

You're probably more familiar with Enterprise PL/I than I am, so I won't
go into any details on new features.

Iron Spring PL/I attempts to be somewhere between Subset G, IBM PL/I 1.1
and Enterprise PL/I, hopefully now including the most used 90% or so of language features. The reason I started writing it was because I was
unhappy with hardware and OS support of existing PL/I compilers.

That is not true at all. :-)

Kednos is no more. However, the IP is still alive and updates to the
Alpha compiler will be available by July. An Itanium port is alive.
However, that is likely to be an intermediate and unreleased port
in the path to x86-64.

There is a port to retarget to LLVM for a Linux and Windows x86-64
targeted port. This is based on the Tru64 compiler which is a
full-ANSI compiler.

Good news. I was going by what Tom told me a while ago.
