in reply to LWP and barewords under strict

A few comments:

You never use $check. One thing I've taken on as a habit is to declare the variables I use as 'my' when I use them. When you pre-declare them in one string as you have with my ($ua, $req, $chrom, $start, $end, $db, $check);, you increase the chance of error when you remove/add them later, as you have in this script. One possible solution is as follows:

my $ua = LWP::UserAgent->new; my $chrom = "7"; my $start = "117287204"; my $end = "117475903"; my $db = "hg11"; my $url = "";
(I also like to indent for readability, but that's more a matter of personal style.)

You also are not properly separating your POST object. It should look something like:

# Indented again my $request = POST $url, ['hgsid' => "6765675", 'g' => "htcGetDna2", 'c' => 'chr'.$chrom, 'l' => $start, 'r' => $end, 'db' => $db, 'hgc.dna.out1' => 'lc', 'boolshad.hgc.dna.rc' => '1', 'Submit' => 'Submit' ];
Note the use of the single quotes around the key, which was missing in your original script. Adding the above fixes allows your code to work as intended.
