pointers

can points get values from the memory which other programs are using????? or isnt this possible

In protected-mode (Unix, Windows, whatever), no. In DOS, it can do anything.

just to confirm, to have a dos program you need to compile it with a 16bit compiler? is that right


Thanks :D

You can have a 32-bit DOS program, but you need an extender. Remember DOS/4GW? That provides a protected-mode environment within DOS.

But ordinary DOS programs, yeah, they were 16-bit.

Not only DOS apps, it has to be a real DOS environment, not some simulated environment in Windows.
