One way of returning two (or more) arrays is by trying the following code. Note that in this example I am returning three array references.
#!/usr/local/bin/perl -w
use strict;
my ($f1,$f2,$f3)=foo();
print "arry1 arry2 arry3\n";
print "----- ----- -----\n";
for my $i (0..(scalar(@$f1)-1))
{
print " @$f1[$i] @$f2[$i] @$f3[$i]\n";
}
sub foo
{
my @$arry1=("a1","a2","a3");
my @$arry2=("b1","b2","b3");
my @$arry3=("c1","c2","c3");
return @_=($arry1,$arry2,$arry3);
}
Should print out the following:
arry1 arry2 arry3
----- ----- -----
a1 b1 c1
a2 b2 c2
a3 b3 c3
