ABSTRACT:
The method divides the buffer memory of an interactive processing and display means in a manner which permits the user to select a portion of a stored image defined by a variable set of address boundaries defining a portion of memory residing within a larger portion of memory defined by another set of address boundaries which in turn resides within a global portion of memory defined by yet another set of address boundaries. The user can vary the variable set of address boundaries so that if they intersect with the address boundaries of the larger portions of memory in which they reside, the buffer memory is updated from a bulk memory.
