in reply to Variables in Regular Expressions?

This is what I used, and yes it does work.

#!/usr/bin/perl $a = "abc"; $b = "def"; $c = "abc leppard"; $c =~ s/$a/$b/; print $c;

I didn't think you could transliterate on that so I tried it and then tried a substitution. To my avail, it worked.
Just so all these other monks that think a transliteration will work, this is what I got when I ran it as  tr/$a/$b/;

Which, I doubt is what he wanted.

PS: May I ask what ~= is? I think you mean =~. :)

UPDATE: It seems that everyone likes to answer this in a minute's time. Chady and some other monk already beat me to it :)
