---Problably all of them.

   If you have been reading job postings in comp.lang.pl1 and other
(job) newsgroups, you would have see that new projects are being
developed in PL/I.

	>Migrating and maintaining existing applications ?

---Certainly.

---The real choices are few.  PL/I is superior to most languages
for general programming.

   You see, PL/I was a significant advance on other languages
when it was introduced in 1966.  Features such as interrupt
handling (great for real-time processing) didn't then exist
in most other HL languages.

   Those features have kept PL/I at the forefront today.

   And the PL/I language has been extended recently with the
new implementations on the OS/2, Windows 95/NT and AIX platforms.
