Thank you all for your help. The reason why I'm putting
a bit of code into the SUBS package is that I've got
about 5 different CGI scripts which get information
out of SUBS - it saves me repeating alot of code. My
solution was as follows. In SUBS:
package SUBS;
use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw ($log $site $base $dbh);
use vars qw ($log $site $base $dbh);
sub connectdb() {
#Open the Oracle database:
my($dbline,@dbinfo);
if (!defined(open(DBINFO, "$base/dbinfo"))) {
die "Can't open dbinfo.\n";
}
while(defined($dbline = <DBINFO>)) {
chomp($dbline);
push @dbinfo, $dbline;
}
close(DBINFO);
$dbh = DBI->connect($dbinfo[0],$dbinfo[1],
$dbinfo[2],$dbinfo[3],
{ RaiseError => 1,
AutoCommit => 1}
);
$dbh->trace(2,"$log");
}
While in db.cgi:
package SUBS;
use SUBS;
.
.
.
&connect_db();
The main difference betwee this example and my original
post was that I am now using use SUBS as opposed to
require SUBS as before. I'm also using 'use var'. SUBS
also now exports only those variables used by db.cgi
in the @EXPORT array. Again, thanks for all your
suggestions.
Stacy.
