I've never used it either and I know nothing about current ownership or
plans.  I just remember that it came up in discussions of what gets lost
in a platform port.

There is a now-moribund PL/I project for the GCC back end:

<http://pl1gcc.sourceforge.net>

and there is a proprietary compiler that runs on Linux:

<http://www.iron-spring.com/about.html>

Both of these emulate IBM PL/I and would likely require a monumental
effort to replace DEC PL/I.
