[A83] Re: homescreen cursor location when ! is closed



The "location of the homescreen cursor" doesnt specifically coincide with 
these edit memory locations, but instead an edit session uses them to keep 
track of boundaries of the variable open for editing and the cursor location 
within the edit buffer. Homescreen input is one form of this edit session 
where the typed tokens go into the ! variable for temporary storage before it 
is parsed. As for the memory locations of where the screen and cursor 
position info is stored when an app or another context is run, I would guess 
Command Shadow, but I'm not certain. Why do you need to know this 
information? Perhaps a more knowledgable person of the topic will give his 
insight when he gets to his Email sometime today. :)
