AHHHHHHHHHHHHHH
NO GOTO PLEASE !!!!!!!!
It is possible............ EVERY GOOD PROGRAMMED WOULD NEVER USE GOTOS....
I used gotos in gwbasic in the msdos days, !!!!!!!! aweful, I used
gotos/jmps in assembly back then.......
in assembly only they are necessary.......
in C they are provided and yet they make the code flow hard to deal with and
dont achieve things any better then using while/loops/fors....
just refer to what Gabriele G. Ponti first wrote, use beark; to get off the
inner loop and a flag to get off the outer one or yet anothe break.
