bit - and, or, xor, not, rshift, lshift bitwise functions
(intrinsic) function and (word1, word2)
(intrinsic) function or (word1, word2)
(intrinsic) function xor (word1, word2)
(intrinsic) function not (word)
(intrinsic) function rshift (word, nbits)
(intrinsic) function lshift (word, nbits)
These bitwise functions are built into the compiler and return the data
type of their argument(s). It is recommended that their arguments be
integer values; inappropriate manipulation of real objects may cause
The bitwise combinatorial functions return the bitwise ``and'' (and),
``or'' (or), or ``exclusive or'' (xor) of two operands. Not returns
the bitwise complement of its operand.
Lshift, or rshift with a negative nbits, is a logical left shift with
no end around carry. Rshift, or lshift with a negative nbits, is an
arithmatic right shift with sign extension. No test is made for a rea-
sonable value of nbits.
These functions are generated in-line by the f77 compiler.
