   IMGDISP dataset frame <keywords>
Parameters:
   dataset | ADDE dataset name and position; specify as alias.position or
             group/descriptor.position; to use the default position,

             (no def for alias or group/descriptor, def=0 for position)
   frame | frame number to display image; specify "OPP" to display image
           on the opposite frame; use CYCLE and SEQ keywords to specify a
           range of frames for maintaining a loop of images (def=current)
Keywords:

   PLAce= | location on frame to place the point specified in LATLON,
            STATION or LINELE keyword; valid options are ULEFT and CENTER
            for upper-left corner and center of the frame, respectively
            (def=ULEFT when LINELE is used, def=CENTER when LATLON or
            STATION is used)
   STAtion= | station ID, e.g., MSN, YSSY, 72201 to place at the frame
              location specified in the PLACE keyword

   DAY= | selects the most recent image from the specified day (def=most
          recent image)
   RTIme=bmin emin | selects the most recent image in the specified range
                     of minutes in the current hour; overrides the TIME
                     keyword (def=most recent image)
   TIMe=btime etime | selects the most recent image in the specified time
                      range (def=most recent image)
*********************  Output Keywords  **********************************
   BANd= | image band number to display (def=existing band if image is
           single-band; no def if image is multi-band)
   EU= | name of enhancement table to apply to the image
   GRAy=NO  | does not display a grayscale bar (def)
       =YES | adds grayscale bar to bottom of image
       =repeat inc start line | user-defined grayscale bar, where:
              repeat - brightess repeat factor (def=5)
              inc - brightness level increment (def=2)
              start - starting brightness level (def=0)
              line  - starting TV line; value must be greater than 0
                      (def=# of lines in frame minus 23)
   MAG=lmag emag | line and element magnification of the data
                   (lmag def=1, emag def=lmag)
   REFresh='command' gfra | runs the commands specified in 'command' after
                            IMGDISP displays the image; you can use (IMA)
                            and (GRA) to specify a frame number for the
                            commands; see McIDAS User's Guide for details
   SIZe=line ele | number of lines and elements of the image to display
                   (def=image size or frame size, whichever is smaller)
   SU= | name of the stretch table to apply to the image
   TEXt='text' fgd bgd | annotation line's text and foreground and
                         background brightness levels (def=X 232 32)
*********************  Multiple Image Load Keywords  *********************
   ALL=bfra efra | displays multiple dataset images; see McIDAS User's
                   Guide for details
   REPeat=num pinc finc | displays num number of images in the dataset;
                          see McIDAS User's Guide for details (def=1 1 1)
*********************  Loop Maintenance Keywords  ************************
   CYCle=inc bfra efra | updates range of frames bfra-efra by displaying
                         the image in the frame determined by the formula:
                           frame=(modulus(time/inc,numfra))+bfra
                         see the User's Guide for details (inc def=1:00,
                         meaning a 1-hour increment, no def for bfra,efra)
   SEQ=bfra efra | updates range of frames bfra-efra by displaying the
                   image in the frame following the frame with the most
                   recent image; selected frame overrides frame parameter
*********************  Miscellaneous Keywords  ***************************
   CAL=QTIR | use quick calibration for faster loads of POES images
   SF=YES | shows the specified frame prior to displaying image (def=NO)
Remarks:
   By default, the upper-left corner of the image is positioned at the
   upper-left corner of the frame.  Keywords LATLON, LINELE, STATION and
   PLACE are used to specify a different image and/or frame position.
   Keyword MAG is used to blowup or blowdown the image.
