Labels.dbf in my vfp98 directory, VFP 6?

>I need to design a label for a client.
>When you issue "CREA LABEL", you get the "New Label" dialog that lists the known Avery labels. The type I need is not in there, but I have the specifications for it (from Word, which does know about this type of label). Where is the metadata stored in VFP that drives the "New Label" dialog? I figure I can add a row and enter the specifications I have.
