Or consider an OO approach, without the sneaky 3 undefs:-
package Spinner;
sub new
{
return bless { position => 0, picture => [ qw( | / - \ ) ] }, shift;
}
sub spin
{
my $obj = shift;
$obj->{position} = ( ++$obj->{position} ) % @{ $obj->{picture} };
print "\b$obj->{picture}[ $obj->{position} ]";
}
DESTROY
{
print "\b \n";
}
package main;
use Win32;
local $| = 1;
print "Doing even more stuff . . . ";
my $spinner = new Spinner;
for ( 1 .. 26 )
{
$spinner->spin();
Win32::Sleep(50);
}
[OT]: Changed jobs then Brian?
