setting new variable to regex of another without changing the other variable in perl


currently i have a Variable named $name which contains "JOHN,SMITH".
What i'm looking to do is take the first letter of the first and last name and assign it to another variable without changing $name.
what i tried was this:
Code:
$OF = $name =~ s/^(.).*,(.).*/$1$2/;
so what i'm getting is a value of 1 for $OF and name is changing to JS.
how do i get $OF to be JS and $name to stay "JOHN,SMITH"
thanks

Edit: figured it out:

Code:
($OF = $name) =~ s/^(.).*,(.).*/$1$2/;

Hi Eppo,

it becomes more obvious what you want to achieve when you split the name at first and then use a regex for each word, here's the example:
Code:
#!/usr/bin/perl

use strict ;
use warnings ;

my $john = "John,Smith" ;

my @name = split ",", $john ;

my $name ;
foreach $name (@name) {
   $name =~ m/(^.)/ ;
   print $1 ;
}
