in reply to Returning multiple values from a subroutine

You are returning a reference to an array, which is a scalar value.
So you need to expect a scalar, and then de-reference it to get at the array values.

Observe:
#!/usr/bin/perl use strict; use warnings; my $currAcct = 1; my ( $subs, $SubId ) = getsubsFromAcct( $currAcct ); my $length = @$subs; print ("No of subs : $length and subs are @{$subs}"); sub getsubsFromAcct { my $acctNum = shift; my @subs = (); my $sbscrpId = 4; @subs = qw| 2 3 4 5 |; return ( \@subs, \$sbscrpId ); }
Prints:
No of subs : 4 and subs are 2 3 4 5

Hope this helps
Darren
