GET3NAME
Type: Verb
Use:  GET3NAME(n) will interpret its immediate argument as a
      catalog slot number and assign adverbs IN3NAME, IN3CLASS,
      IN3SEQ, and IN3TYPE to correspond to that slot.  If the
      input value of IN3DISK is zero, it will be changed to that
      corresponding to USERID's image, but only if such a change
      is required to avoid duplicate names (i.e. the same image
      name on different volumes).

      Example:
         GET3NAME(34) will fill IN3NAME, IN3CLASS, IN3SEQ, and IN3TYPE
         with the 34 catalog entry on disk IN3DISK.  If IN3DISK is
         zero, all disks are searched and, only if needed to avoid
         duplicate names, IN3DISK is set to the volume containing the
         USERID's image.
Input adverbs:
  immediate argument is a catalog slot number.
  IN3DISK.....The disk the catalog is on.  0 => any
  USERID......The logon user number of the image's owner.
              0 => current logon #,  32000=> any user #
Output adverbs:
  IN3NAME.....Third image name (name)
  IN3CLASS....Third image name (class).
  IN3SEQ......Third image name (seq. #).
  IN3TYPE.....Third image name (type).
  IN3DISK.....Disk drive # of third image (output only if
              needed to avoid duplication).
