Displaying Memory Using a Support Processor

      Disclosed is a method for displaying the contents of memory,
using a support processor screen interface, without making a separate
memory screen for each block of memory.

      There is too much memory on any computer system to have a
support processor screen for each block of memory.  A way was needed
to display memory without making multiple support processor screens.
At the same time, it should be as easy to use as possible.

      To solve this problem, new code was written that allowed the
user to scroll up and down through one screen of memory data.  As
part of the implementation, three screen commands were created and
one was modified. These are described below:
      sam (Screen Add Memory) - Will determine how many addresses the
screen will scroll up or down each time the "page up" or "page down"
key is pressed.
      sad (Screen Add Device) - This command already existed for
displaying non-memory chip data.  It was changed to accept memory as
a valid chip-type.  A memory offset field was added for the memory
chip-type that allows different lines of memory to be displayed on
one screen based on the origin and the offset (sao and sav).
      sao (Screen Add Origin) - Contains a variable origin which is
the base address from which all addresses are offset.  This value is
updated by the amount specified by the "sam" command every time the
"page up" or "page down" key is pressed.
