This should be easy, but I'm haven't stumbled upon the answer yet.

I can successfully use the tr/// operator if both search list and replacement list are hardcoded. ie. 

my $s =~ tr/abcd/ABCD/;

But the following does not produce the same result: 
my $replace = 'ABCD';
my $s =~ tr/abcd/$replace/;

Any clarification you can provide would be greatly appreciated. Thanks.
