Hi,

Newish Perl user trying to use do $filename; to read configuration data from a file.

Configuration file consists of:

# set up the database connection variables

$db_username = '';
$db_password = 'somepassword';
$db_host = 'localhost';
$db_database = 'adb';
$db_table = 'notactual';
[download]

The script consists, so far, of the following code:

#!/usr/bin/perl -w
 
use strict;
use diagnostics;
 
my $preprocessdir;
my $db_username;
my $db_password;
my $db_host;
my $db_database;
my $db_table;
my $db_tracelog;
my $conf_file;
my $return;
 
 
$conf_file = "/home/kuser/dbconnect.inc.pl";
unless ($return = do $conf_file) {
warn "couldn't parse $conf_file: $@" if $@;
warn "couldn't do $conf_file: $!"    unless defined $return;
warn "couldn't run $conf_file"       unless $return;
}
 
print $db_username;
print $db_password;
print $db_host;
print $db_database;
print $db_table;
[download]

When run it gives the an error for each of the print lines

Use of uninitialized value in print at ocrgqx_audit_report.pl line 30 
+(#1)
    (W uninitialized) An undefined value was used as if it were alread
+y
    defined.  It was interpreted as a "" or a 0, but maybe it was a mi
+stake.
    To suppress this warning assign a defined value to your variables.

I am trying to set variables within the script using a configuration file

So I guess I've got some syntax wrong but I can't see what. Follow up query: am I using do appropriately for configuration files - I'm aware of use Safe and will when this first level of syntax is sorted - may lead to a further question ;-)

Thank you in advance

Steve
