GET4NAME
Type: Verb
Use:  GET4NAME(n) will interpret its immediate argument as a catalog
      slot number and assign adverbs IN4NAME, IN4CLASS, IN4SEQ, and
      IN4TYPE to correspond to that slot.  If the input value of
      IN4DISK 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:
         GET4NAME(34) will fill IN4NAME, IN4CLASS, IN4SEQ, and IN4TYPE
         with the 34 catalog entry on disk IN4DISK.  If IN4DISK is
         zero, all disks are searched and, only if needed to avoid
         duplicate names, IN4DISK is set to the volume containing the
         USERID's image.
Input adverbs:
  immediate argument is a catalog slot number.
  IN4DISK.....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:
  IN4NAME.....Fourth image name (name)
  IN4CLASS....Fourth image name (class).
  IN4SEQ......Fourth image name (seq. #).
  IN4TYPE.....Fourth image name (type).
  IN4DISK.....Disk drive # of fourth image (output only if
              needed to avoid duplication).
