Re: A86: VAT size
Some questions about calc resets...
1. Since stat vars are present at first power-up and can't (normally)
be deleted, can I trust that their positions in the VAT will not
change? Will they always be at the beginning, is what I'm asking I
guess...
2. What other than a wipe of the VAT, does a mem reset do? (if
anything?)
3. If I were to change the _p_ptemp and _ptemp_end pointers to their
default first power-up values, would the calc think the memory had been
wiped? This is why I need an answer to number 1; 'cause I would like
the calc to think it has been mem wiped, but I want to make sure the
default vars are there.
If any of that makes sense...
