Q about loading BASIC programs

[Moll <Mollyzkoubou@Spam.BettyKate.Spam.Spam.Spam.Dosius.Com>]

A problem I have had with code I wrote to DMA a program into emulated 
6502 space (I tried this on two of my Apple ][ emulator projects) was 
that when I ran the program, accessing a variable would cause code to be 
overwritten.

Obviously some POKE has to be set to point to the top of the program 
space, but I am not sure which one.

Thanks for any help.

Moll.
