HELP SECTION

PUTVALUE
Type: Verb
Use:  PUTVALUE store an image value at the image location
      specified by PIXXY (in pixels).  It stores both the old
      and new image values in the history file.  There are NO
      defaults and you are changing your data - be careful.
Adverbs (input):
  INNAME......Image name(name).        Standard defaults.
  INCLASS.....Image name(class).       Standard defaults.
  INSEQ.......Image name(seq. #).      0 => highest.
  INDISK......Disk drive # of image.   0 => any.
  PIXXY.......(X,Y,...) pixel location in image.  NO default.
  PIXVAL......Intensity at this pixel in image units: NO default
  OPCODE......If 'BLNK', ignore PIXVAL and store a magic-blanked
              value in the pixel.  Otherwise store PIXVAL.
  DOHIST......If < -1.5, the transaction will not be recorded in
              the history file.  Otherwise the previous and new
              pixel values and the pixel coordinates are put in
              the history file since this is a potentially
              important operation.
