Thank you for the explanation. It sounds a bit like the setext format. I understand that there is a pod viewer for Mac, called Shuck. I remember having seen a URL that started with "pod:" - are there really Web browsers out there that read pod, or was that a joke / a wish ? Is there a specification somewhere for the pod format ? Sorry to digress that much from MacPerl. On the other hand, converting between those formats is best done with Perl ;-)} . Pter Van Avermaet
