We're informed that IBM makes quite a bundle from PL/I,
and other companies (e.g., Liant and UniPrise) are in
the business of supplying PL/I compilers on varous systems.

You bet it's not!

On the contrary, they are excellent examples, and demonstrate
the adaptabiity, suiltability & portability of PL/I for
large-scale projects.

It's one of the enduring success stories. The features
in PL/I were so advanced that the language didn't need continual
updating over the years (like some other languages did !).
Recall that PL/I has been going for some 30 years now.
Some of the features that were advanced for the time include
array operations and error interception and handling.
