I need to get my autoit script to LOCK a memory address.. How exactly would i go about this? The address is an 8 byte integer...

I am not sure this is possible or impossible, but you need to search the forum for _Mem*() functions. Someone has created a whole list of functions that deal with memory. A quick search should give you some clues.

a LOCK call isnt made AFAIK.

but there is an open-close read-write. (wonder who made that)

they should give you an example on how to do it.

check my sig.

Do you actually know what you want? An "8 byte integer" is presumably a 64-bit memory address which would mean you are using a 64-bit version of Windows, correct? And what do you mean "LOCK" it? Lock it form what? Being read? Being written to? Being executed as code?

I mean locking it so that hte value cannot be increased or decreased.

Then you need to use the Windows API function VirtualProtectEx with the PAGE_READONLY flag. Note that setting the address to read only will cause an access violation if something tries to write to that address, anyway.
