It appears that there is something strange with the hash. If I do something like this : 
$vHash{"101010"}{"S0"} = "text";
$vHash{"101010USED"}{"S0"} = "text";
if (!exists($vHash{"101010"}{"S0"}{"SYSTEM"})) {
    $vHash{"101010"}{"S0"}{"SYSTEM"} = "TEXT";
    print "First<br>";
}
if (!exists($vHash{"101010USED"}{"S0"}{"SYSTEM"})) {
    $vHash{"101010USED"}{"S0"}{"SYSTEM"} = "TEXT";
    print "Second<br>";
}

I only get First printed. If I happen to take the USED in the second if statement and change it to USED101010 and then retry running it I get First and Second print out. Does Perl just look at the first n characters in a hash? Does it see it starts with numbers and then only takes the numbers up until a non-numeric value? Does anyone have an idea to what is happening? Thanks in advance for any help.
