   Heh !!! :-)

   Well, I don't see FORTRAN as a "pig" really - a totally
   useful, still well-supported, lang. Still do little FORTRAN
   utils just to stay in practice.

   Anyway, sometimes you have to nest/flag deep if/then's
   and whiles and such so deep that there's really no
   clean escape in a special or exception condition. This
   is where a 'bail-out' GOTO or two can make yer code
   a LOT simpler/smaller. Not 101% aesthetic, but it works
   very well. Use conservatively.

   Ultimately you judge code by what it DOES - less by
   to how it "looks". It's all "working the machine".
