Was playing around with it today, and noticed that while you can assign to
it (i.e., it is not "read-only" in GAWK terms), changing it does not
actually change the process group ID. Would be nice if it did. I.e.,
setting that array element would cause GAWK to invoke the appropriate
setpgid() call to change GAWK's process group ID [*].

Note, incidentally, that (as currently written, that is, w/o the
improvement suggested above) changing that array element would render false
the assertion (in the man page) that the array element contains "The value
of the getpgrp() system call.". Implementing the suggested change would maintain the accuracy of that assertion.

BTW, what sort of contents does this (and similar) PROCINFO element(s)
contain on non-Unix/Linux system (e.g., a "native" Windows port - not
Cygwin, of course, where, I expect, it would return sensible values as
under Unix/Linux) ?

[*] Note that I can, of course, change the process group ID of a GAWK
program, using the call_any() extension, but this is not available to most users.

OK, thanks.

It's about what I would have expected.

Just out of curiosity, from whence did your version of GAWK come?
Who compiled it?
