Programmers,

I just created a program launcher that I'd like re-activate on 
CTRL-RESET.  I know that I have no control over the programs being 
launched and that there will be a chance that my reset vector bytes 
($3F2-$3F4) may get hosed, but in the event they do not, where is the 
least likely place someone will use memory?  I tried page $BF with the 
worse results.  Right now I am starting at $310 with good results, but 
I'd like better results if possible.

Thanks.

P.S., I should mention that this is for the //e only.  The main program 
is in AUX memory, my reset routine on CTRL-RESET copies back to main 
memory.  I cannot run from AUX memory since I use self-mod code and need 
a fresh instance on restart.

Thanks again.
