or you could just make a DLL to read/write anywhere ;)
but on anything newer than a 286 there is something called "protected mode" which means you can only read/write in parts of memory reserved for that program. and if you write anywhere else you get a memory access violation. THAT'S what causes those fatal program errors in windows ;)
but if you're just trying to access.. say, a memory block some other userlib has created, that's entirely possible (and easy).
so what do you want to do?
