in reply to problematice metashar regexp

One of the things that may go wrong is that you substitute in the result of a substitution. Consider the first character 'h', it's replaced by '^', but '^' can in turn be replaced by '~', depending on the order of the keys, something you don't control in a hash. Maybe this effect is intentional, but if not, it could be the source of your problem. If so, replace the global substitution by a while over the characters of the string.

Hope this helps, -gjb-

    This is most likely the problem.

    I have to say, this was pretty darn intuitive of you, and I really appreciate the help.

    Since I'm trying to stop benig such a hack (ugly code, procedural, use strict, etc.), is this the prettyiest way to while over a string?

    #!/usr/bin/perl -w use strict; my $string="wheristhelove"; my @array=split(/\s*/, $string); foreach (@array){ ...
    Again, thank you so much for your help!
