( #3333=superdoc: print w/replies, xml ) Need Help??

Try concatenating the vars for use in the substitution:

use strict; use warnings; my $lhs = '(\d*?)-(.*?)-(.*)'; my $rhs = '$1.$2.$3'; while ( my $var = <DATA> ) { chomp $var; $var =~ s/$lhs/$rhs/ee; print $var, "\n"; } __DATA__ 123-456-789 -456-789 789

Output:

123456789 456789 789

From the error message, it appears that the results of the first evaluation is ambiguous to the interpreter when it attempts to evaluate it without the concatenation operator.

    [stevieb]: it's Quebec... they do weird stuff there :) In the mountains, it is *mandatory* for trucks to use tire chains. Many passenger vehicles do as well (but it's not mandatory for them)
    [perldigious]: That stuff can hit fast... like what we just got where I'm at. Saw a few people who had slid OUT of the roundabout I have to drive through to get to work, not used to the ice yet, take awhile to get the hang of it again and make vehicle adjustments.
    [stevieb]: man, when the roads are glare ice, I don't even bother going to work or out... unless I absolutely have to, or was already out in the first place
    [choroba]: Tire chains are mandatory here in mountains, and the only unprepared each year are gritters
    [stevieb]: I have a 3 day winter survival kit in my vehicle in the event I get snowed in in the mountains (which has happened before due to avalanches closing the roads (and once in the summer due to a massive forest fire that trapped us
    [perldigious]: a handful of people in my work area did not make it, but I live pretty close and it's flat the whole way, so I didn't have any trouble. The roundabout is the worst thing I have to negotiate.
    [thezip]: G'day all!
    [perldigious]: Well, that and dodging the people who forget how ice works right away. :-)
    [stevieb]: hey, thezip
    [perldigious]: I don't miss having to drive up and down in elevation on roads that are iced over, I white knuckled gripping the steering wheel every time I had to where I used to live.
