No, the 'functions' I was referring to is the facility for user-defined
functions.  Apparently Kernighan's latest version of AWK, in use at AT&T
Bell Labs by Jon Bentley, CACM's "Programming Pearls" columnist,
allows definitions of recursive AWK functions.)  Guy Harris suggests
these features might be in SVR2, but I didn't quite follow his
description of what was in which release.

(Bentley gives, in AWK, a subroutine library of various sorting and
searching routines, pointing to particular spots he had trouble
implementing even though he had formally verified the specifications.)
