As others have mentioned, without some more information we can't give you help that is specific to your problem. As a general pointer, though (and in an attempt to teach you how to fish), please see the section entitled "Loop Control" in perlsyn and the individual functions in perlfunc. There are three basic commands:

• next: starts the next iteration of the loop (the continue block, if any, is executed)
• last: immediately exits the loop (the continue block, if any, is not executed)
• redo: restarts the loop block without evaluating the conditional again (the continue block, if any, is not executed)

Please note that there are situations in which the next, last, and redo commands cannot be used (see perlfunc).

TOP:
for (my $i = 1; $i < 10; $i++) {
    if (5 == $i) {
        next TOP;
    }
    print "Iteration $i\n";
}

It will, of course, print all the integers from 1 to 9 except for the number 5.

Same ol, same ol - show us some code, show us what you expect, show us what you get. There is even less here for mind reading than usual; I suspect you are not very strong in the force, but we can help with that if you do the exercises.
