Ken,  this is undeniably correct other than the 20 lines that $SMG is merely
a default.  You can set an alternate value when you use the SMG$CREATE_
_VIRTUAL_KEYBOARD. The $SMG documentation gives a better description.

I also have a related question.  To use the SMG$RECALL_INPUT_LINE you must 
you must first have the Screen Management stuff running (ie. create a virtual
keyboard, save the physical screen etc.).  I'm trying to write a vms 'finger'
and would like to get the person's last command instead of using $GETJPI to 
find their image.  Is there a way to recall the last line of another process 
without using Screen Management utilities?  Possibly through IO$ calls? Any
chance of it being accessible through the device driver stuff?


Thanks!
