HELP SECTION

SQASH
Type: Task
Use:  Task to collapse several planes in a cube into one plane
Adverbs:
  INNAME......Input name of image(name).     Standard defaults.
  INCLASS.....Input name of image(class).    Standard defaults.
  INSEQ.......Input name of image(seq. #).   0 => highest.
  INDISK......Disk drive # of image.         0 => any.
  OUTNAME.....Output name of image(name).    Standard defaults.
  OUTCLASS....Output name of image(class).   Standard defaults.
  OUTSEQ......Output name of image(seq. #).  0 => highest unique
  OUTDISK.....Disk drive # of Output image.  0 => highest with
              space.
  BLC.........The bottom left-hand pixel of the input image
              which becomes the bottom left corner of the
              subimage.  The value (0,0) means (1,1).
  TRC.........The top right-hand pixel of the input image
              which becomes the top right corner of the
              subimage.  The value (0,0) means take the top
              right hand corner of the image.
  BDROP.......If > 0, use axis BDROP only
              If < 0, use all axes >= -BDROP
              Note BDROP > 2 or BDROP < -2 is required here.
  DPARM.......Control flags:
              (1) 0: average; 1: sum; 2: maximum; 3: minimum
              (2) > 0  => ignore blanks unless all contributing
                          planes are blank at the pixel
                  <= 0 => if any plane is blanked at a pixel,
                          blank that pixel on output
