FWord

For other uses, see F word (disambiguation).

FWORD stands for Far Word.[1]

The df/fword statement's main use is declaring 48 bit far pointers for use in 32 bit protected mode on the 80386 and later. Although it is possible to create an arbitrary 6 byte variable, the directive is best used for 48 bit far pointers on the 80386.[2]

Examples

JMP FWORD PTR [FWordPtr]

JMP 00FF:00FFFFFF
