Re: A85: Link Port

 The homescreen is concidered an application on the TI82, but some of the
things below are not. On the TI82 i optained this list of applications using
an interrupt driven program.

40 Homescreen
41 Link
45 Graph
46 Mode
47 Program (edit)
48 Program (name)
49 Window
4A Y-var input
4B Table
4C Table set
52 Error

Each application on the TI82 has its own input handler and a code which
identify the application, the cdoe is a byte and it is listed above. On the
TI82 the code is stored at 8121. My guess is that on the TI85 it is stored
at 819Ah. Maybe someone could make a program which checled if this was
correct, and if it is post the codes for the applications to this list.
