I made a stab at writting some BSAVE and BLOAD type routines
for PBCC. Run the program to see how long it takes for different
screen modes..

Most Console Screen NON Standard modes I've tried worked properly
except 50x79 and only sometimes. I haven't tried them all yet.
All Standard modes seems to work well.

You are welcome to use the routines at your own risk.


 '-------------------------------------------------------------------
 ' BSAVEs Copies the current screen to a file. It can be any screen
 ' mode size, 50x80, 70x80, 20x20, etc. The number of Screen rows is
 ' passed through the lRows Variable and the number of columns is
 ' passed through the lColumns Variable. The Global Variables and
 ' Global Arrays are used by both BLOADs and BSAVEs, they have to be
 ' included in your code.
 '
 ' BLOADs will copy the screen from the file back to the Screen.
 ' As with BSAVEs, you'll need to pass the Console Screen Size through
 ' the lRows and lColumns variables.
