BIT(3F)                 COMMAND REFERENCE                 BIT(3F)



NAME
     bit - and, or, xor, not, rshift, lshift bitwise functions

SYNOPSIS
     (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)

DESCRIPTION
     These bitwise functions are built into the FORTRAN 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
     unexpected results.

     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 with a positive
     nbits, is a logical right shift with no sign extension.
     Lshift with a negative nbits, is an logical right shift with
     no sign extension.  No test is made for a reasonable value
     of nbits.

FILES
     These functions are generated in-line by the f77 compiler.
