It took me over half an hour of fumbling, until i understood that you meant the
"while (fgets(buf, sixeof buf, fpin))" if that's right. then i fumbled the
ball because i used your pointer example rather than the indexing-into method,
case 'B'.
Just a FWIW, But for middle-involved cases like this program--what? a couple k lines
long--when i get wedged like this, i almost always break it down into like a
main{
fgets()
}
THEN:
skiptags()
i didn't figure this 'keep it simple, Sire' paradigm until a few [7-9,10] years ago.
that's godawful late to learn new tricks. it's hard to understand 35 lines of code
in the midst of 2400 :_)
