Hi Mike
I thought you may be interested in an alternative.
$str =~ m/\Q$substr/g;
print pos($str) - length($substr), "\n";
which is similar to 'print index $str, $substr, "\n"' but has the
advantage that it works on a regular expression. It can also be put into
a loop without troubling to use index's third 'position' parameter.
while ( $str =~ m/\Q$substr/g )
{
print pos($str) - length($substr), "\n";
}
Cheers,
Rob
