- The IIBBIITTSS, IIIIBBIITTSS, JJIIBBIITTSS, and KKIIBBIITTSS intrinsic functions extract a
- sequence of bits. They accept the following arguments:
-
- _i Must be of type integer. For IIIIBBIITTSS, must be of type
- integer (KIND=2). For JJIIBBIITTSS, must be of type integer
- (KIND=4). For KKIIBBIITTSS, must be of type integer (KIND=8).
-
- _p_o_s Must be of type integer. It must be nonnegative and _p_o_s +
- _l_e_n must be less than or equal to BBIITT__SSIIZZEE (_i).
-
- _l_e_n Must be of type integer and nonnegative.
-
- These are elemental intrinsic functions. The names of these
- intrinsics cannot be passed as arguments.
-
- RREETTUURRNN VVAALLUUEESS
- The result type and type parameter are the same as _i. The result has
- the value of the sequence of _l_e_n bits in _i beginning at bit _p_o_s
- right-adjusted and with all other bits zero.
-
- The bit model defines the model for the interpretation of an integer
- value as a sequence of bits. For more information on the bit model,
- see the MMOODDEELLSS(3I) man page.

- EEXXAAMMPPLLEESS
- IIBBIITTSS((1144,,11,,33)) has the value 7. In this example, the bits are numbered
- from right to left, so they are extracted from right to left.
