OFFSETSIZE

The OFFSETSIZE option determines the size of OFFSET variables in 64-bit applications.

                  .-4-.      
>>-OFFSETSIZE--(--+-8-+--)-------------------------------------><

4

Under OFFSETSIZE(4), all OFFSET variables are four bytes in size. This is the default.

8

Under OFFSETSIZE(8), all OFFSET variables are eight bytes in size.

Any code that shares either OFFSET or AREA variables must be compiled with the same value for the OFFSETSIZE option.

The OFFSETSIZE option is ignored if the LP(32) option is in effect.
