ROMODE
Type:  Adverb (real scalar)
Use:   When an image is too large to fit in one TV memory plane,
       it is possible to load portions of the image into more
       than one TV memory.  Then, one may view any contiguous
       512 x 512 portion of the image.  ROMODE specifies how
       many channels are used and their spatial configuration.
       Valid values can be 41, 31, 21, 12, 13, 14, and 22 where
       the tens digit gives the number of planes on the X axis
       and the ones digit gives the number of planes on the Y
       axis.  Thus, ROMODE = 41 requests that 2048 x-pixels by
       512 y-pixels be loaded to the TV by TVROAM (if the image
       is big enough for that) and ROMODE = 22 requests a 1024
       by 1024 image.  The defaults are set by the map size
       (as limited by TBLC, TTRC, TXINC, and TYINC).  They try
       to load as big an image as possible and prefer mode 22.
Verbs:
  TVROAM.....Load image to TV channels, then roam
  SETROAM....Reset channel spatial configuration, then roam
