in reply to DBI Style Inquiry

You could "name" your first parameter by assigning its value to a lexical. Like chomp(my $param = $_[0]);. But that's not really much change, and that's up to you.

However, there is a problem with your code. The "return" statement exits the sub immediatly, and everything below that point is skipped. Besides, you assign the result of fetchrow_array() to an array that you never use (you could have written return $sth->fetchrow_array();). If you want the end of the sub to be run, you should have something like:

sub get_loc { ... my @loc = $sth->fetchrow_array(); $sth->finish; $dbh->disconnect or die "Error disconnecting: $DBI::errstr\n"; return @loc; }

    Concerning the return statement, apparently it is commonly known that the subroutines exit there but I was ignorant about that fact (I've never taken a programming class, to be honest). Thank you for your input!
