*RECURSIVE*
An optional clause that allows COBOL programs to be recursively
reentered.
You can specify the RECURSIVE clause only on the outermost program
of a compilation unit. Recursive programs cannot contain nested
subprograms.
If the RECURSIVE clause is specified, program-n
I wonder if specifying this leads to compilers doing (optimised)
tail-recursion - where appropriate.

Unfortunately, probably not. Most of the languages that support
tail-recursion are dynamically typed or require annotations. Probably a
bridge too far for COBOL.

Yes, very verbose.
And yes, recursion is possible, but you must specify "IS RECURSIVE" on the
PROGRAM-ID. Not sure what having nested programs has to do with that, though.

It's never a good idea in an interview to say that you run pirated software.
But for those who have zPDT or some other legal platform, I'd mention it.
Likewise those running OS/VS2 R3.8 on Hercules - dated, but a lot of things
carry through.

My first and only recursive program was written in PL1. To avoid a GOTO.
Wrong! S80A abend. Would probably work today with copious amounts of
