Hey toolic, thanks for the reply.

Ok I was afraid of that... Thanks

Is there an easier way (less lines) that I could use with my version like my previous example (i.e. $str = $str2 =~ s/pattern/replace/r; ).

The only way I can think to do this without changing the original string is:
my $str1 = "How-Are-You-Doing" my $str2 = $str1 $str2 =~ s/-/ /; print $str2; ____OUTPUT____ Hello How Are You Doing

     perl -ne '(my $foo = $_) =~ s/-/ /g;'

    The assignment returns an lvalue which then gets the substitution run on it. Basically the same as yours, just in one statement.
