So many people replied so quickly, thank you all!<br>
<br>
I should have been more clear; '$foo' is set further up; I set in manually for this email only.<br>
<br>
I've got this working (real-world where I want two variables):<br>
<br>
my ($bar, $baz)=$foo=~/(\w+-\d+)-(\d+)/;<br>
<br>
May I extend the question?<br>
<br>
How would I go about working with '$1', '$2', etc if I wanted to do something odd, like say (totally fabricated, broken example):<br>
<br>
my $bar="$2 - $1"=$foo=~/(\w+-\d+)-(\d+)/;<br>
<br>
Again, thanks all. This list rocks, if only because of the enthusiasm shown for code optimization (of course, for more reasons, too!).<br>

Hi all,<br>
<br>
I've got a simple problem I often come across, and I've got a way to make it work. However, I've always felt there must be a more ... elegant way of doing it.<br>
<br>
For example, let's say I want to copy a variable and strip a bit off the end;<br>
<br>
my $foo="ABC-987-01";<br>
my $bar=$foo;<br>
$bar=~s/(\w+-\d+)-\d+/$1/;<br>
# $bar now 'ABC-987'.<br>
<br>
That's three lines. Is there a way to do this in one line? Specifically, is there a way to assign '$1' to a new variable in one go?<br>
<br>
Thanks!<br>
<br>
Madi<br>
