Hi Team,
Can someone explain what is wrong happeneing here ?
$ perl -e 'use Business::ISBN; $isbn_object = new
Business::ISBN('0-59610-206-2');print $isbn->as_string;'
Can't call method "as_string" on an undefined value at -e line 1.
$
John pointed out one mistake. The other mistake is your use of single
quotes around the ISBN.
$ perl -MBusiness::ISBN -le '
$isbn = Business::ISBN->new("0-59610-206-2");
print $isbn->as_string;
'
0-596-10206-2
$
