Hi
Can somebody please help me :
I'll like to have the code of a simple example of several different texts 
stored in several different text buffers . I'll like also to know how to 
switch the screen display from one to the other.
On the other hand, Iam also interested in finding out the first and last line 
number displayed on the screen.
Best Regards
Daniel Gaudry
