clancy, i can't argue with you. my desired usage of break is really just a
cover-up for a goto. i know.
it makes no logical sense but i think i'd sooner adopt oop than gotos. my
mom taught me to program back in the late 70s and early 80s. she was an old
hand. when FORTRAN 4 came out she thought it was the bees knees. when Z80
micros with MS-BASIC came out, she thought they were cute. when turbo pascal
came out on CP/M, she was impressed and taught me to quit using gotos.
so while it makes no logical sense, perhaps you can see that it makes
emotional sense.
