I know that the video screen text buffer is located at $B800:$0000 for the CGA.
Is there any way for my code to figure out its location in general?  In parti-
cular, is there some Reserved Memory Location which points to the screen buffer
or is there a software interrupt or DOS function call which will return the
screen buffer address?

Thank you,
Daniel Lewart
