Specifying Sub-Image

In all MIDAS commands which accept images as parameters you can also provide subimages in the syntax specified above.
For example, the command LOAD/IMAGE loads an image into the MIDAS display (window). Then,
Midas 567> LOAD/IMAGE mygalaxy
would try to display the whole 2-dim image mygalaxy.bdf, whereas
Midas 568> LOAD/IMAGE mygalaxy[@100,@200:@199,@299]
would only load a 100x100 subimage of mygalaxy.bdf beginning at the 100th x-pixel and 200th y-pixel.
