[Koha-devel] Re: [Koha] Z3950 Server, MARC::Record, how to build a record for Koha

[Mike Hansen]

Hello,
        You might want to try $record->leader('                   '); right 
after you create the record object.  I am not familiar with the purpose of the 
leader so you may want to fill it with something more meaningful ;-]
