Re: How do I pass a sequence of variable names to a subroutine one at a time?

[ar0n]

How about:

use strict;

foreach ($query->param) {
    do_stuff($_) if /^c\d+$/;
}

sub do_stuff() {
    my $cd = shift;
    my $value = $query->param($cd);
    # blah
}

param() returns the names of all the parameters when called with any arguments. See the CGI docs.
