EXTDEST
Type: Verb
Use:  Deletes any extension file associated with an image.  The
      INNAME and INEXT adverbs must be specified.  EXTDEST may
      be used to destroy an unexpected "extension" file such as
      one created by a task that ABORTed before updating the
      catalog.  Simply set INVERS to one higher than the
      highest in the header (use IMHEADER or QHEADER to check).
Adverbs:
  INNAME......Image name(name).        Standard defaults except
                                       that blank is not allowed.
  INCLASS.....Image name(class).       Standard defaults.
  INSEQ.......Image name(seq. #).      0 => highest.
  INDISK......Disk drive # of image.   0 => any.
  INEXT.......Extension file type.     No defaults.
  INVERS......Extension file version. -1 => all of type INEXT
                                       0 => highest.
