Hpmh. The HPUX man page for plain awk says

-F fs Specify regular expression used to separate
fields. The default is to recognize space and tab
characters, and to discard leading spaces and
tabs. If the -F option is used, leading input
field separators are no longer discarded.

which makes me think we are treading on mighty thin ice here --- there
are lots of different versions of awk around, and some of them are
probably going to treat -F '.' as a regexp.

I'd suggest splitting the input with something more standardized.
Perhaps

sed 's/\./ /g' | $AWK '{printf ...
