While stepping through the code I wrote, I distinctly noted that the substitution on $_ did NOT affect the array and vice versa. If anyone insists on adding or deleting elements of an array from within a loop, you can ... you just have to update either $_ or what $_ is aliased to, like the original code I posted.
Thanks, John, for reminding me of glob. It does exactly what I need. Perl has so many parts, it is easy to forget many of them.

From perlsyn: If any part of LIST is an array, "foreach" will get very confused if you add or remove elements within the loop body, for example with "splice". So don't do that. -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
