in which case a simple regular expression match is probably what you want:

if ($string =~ s/(\d)//) {
    my $digit = $1;
    ...
} else {
    print "No digit in '$string'\n";
}

which finds and removed the first digit from $string. Putting the substitution inside an if allows you to deal with not finding a digit.

True laziness is hard work
