DRI is still in business, but they are now into things like GEM and
Concurrent DOS.  They haven't been in the language business for some
time - I'm not even sure that they will sell you anything;  it will
certainly not have been worked on in several years ...

PL/M is related to PL/I only in some of the low-level syntax.  The
high-level syntax and the semantics are quite different.  I'm not
sure that DRI ever marketed a PL/M compiler, though Gary Kildall did
write the first Intel PL/M compiler and used the language quite a bit
in CP/M.

The PL/I compiler that DRI had for the 8080 and 8086 was a far cry from
a Subset G PL/I compiler- it was more like Fortran with semicolens and
structures (RECORDs for you Pascal types).  It was also full of
horrible bugs and only supported the small model.  I have had the
misfortune to have to convert a significant amount of code from real
Subset G compilers to the DRI PL/I compiler and take my word for it,
you don't want it if you can possibly avoid it.
