in reply to Variable scope in while loop

#1 is eternal because the my re-declares $number each time such that it gets reset to undef.

#2 won't compile because you are using strict w/o declaring $number w/ my.

#3 works because you put my $number outside the loop so that when the loop loops, $number contains the value you assigned to it instead of getting reset.
