A contiguous group of bits within a binary pattern; they are specified by a starting bit position and length. The functions IBSET, IBCLR, BTEST, and IBITS, and the subroutine MVBITS operate on bit fields.
A contiguous group of bits within a binary pattern; they are specified by a starting bit position and length. Some intrinsic functions (for example, IBSET and BTEST) and the intrinsic subroutine MVBITS operate on bit fields.
A bit field is a common idiom used in computer programming to store a set of Boolean datatype flags compactly, as a series of bits. The bit field is stored in an integral type of known, fixed bit-width. Each Boolean flag is stored in a separate bit.
