Notice that on the page you specified, it lists POINTER as 4 bytes for 32-bit applications and 8-bytes for 64-bit applications.   

In QB64 _OFFSET changes size based on the bits of the EXE which you create.  In a 32-bit EXE, _OFFSET is a 4 bytes INTEGER.  In a 64-bit EXE, _OFFSET is an 8-byte INTEGER.
