Well I don't know much about deleting vars but in terms of changes to
the graph format or draw screen, on the 85, you can just have this at
the beginning of the prog:

:STPIC PTEMP
:STGDB GTEMP

and at the end

:RCPIC PTEMP
:RCGDB GTEMP

this would restore the graph, including any drawings such as inverse
functions, ect.
