The tag you are looking for is
<code> or
<c> - wrap your entire source block in this and it will likely produce the result you are looking for. See
Writeup Formatting Tips and/or
Markup in the Monastery.
Assuming your label syntax follows the following prototype:
LOOP_A: for (my $i = 0; $i < @array1; $i++) {
LOOP_B: for (my $j = 0; $j < @array2; $j++) {
LOOP_C: for (my $k = 0; $k < @array3; $k++) {
print "$i, $j, $k\n";
next LOOP_A if $j == $k and $i == $k;
}
}
}
you do not have a syntax error in your labeling. Post the sample code where perl cannot locate the label, and we'll help you see the issue.
Side note: I am guessing from your for condition that you are using C-style for loops and not Perl-style for loops. It's not an error, but they are more error prone and require more typing.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
