NAME
     IOR, IIOR, JIOR, KIOR - Performs an inclusive OR

SYNOPSIS
     IOR ([I=]i, [J=]j)
     IIOR ([I=]i, [J=]j)
     JIOR ([I=]i, [J=]j)
     KIOR ([I=]i, [J=]j)

IMPLEMENTATION
     UNICOS, UNICOS/mk, IRIX systems

     CF90, MIPSpro 7 Fortran 90, MIPSpro Fortran 77

STANDARDS
     Fortran

     Fortran extensions:  IIOR, JIOR, KIOR

DESCRIPTION
     The IOR, IIOR, JIOR, and KIOR intrinsic functions perform an inclusive
     OR.  They accept the following arguments:

     i         Must be of type integer.  For IIOR, must be of type integer
               (KIND=2).  For JIOR, must be of type integer (KIND=4).  For
               KIOR, must be of type integer (KIND=8).

     j         Must be of type integer with the same kind type parameter as
               i

     These are elemental intrinsic functions.  The names of these
     intrinsics cannot be passed as arguments.

RETURN VALUES
     The result type and type parameter are the same as i.  On IRIX
     systems, the result can be affected by the -i option on the f90(1)
     command line.

     The result has the value obtained by combining i and j bit-by-bit
     according to the following truth table:

          ----------------
                  IOR (i,
          i   j     j)
          ----------------
          1   1       1
          1   0       1
          0   1       1
          0   0       0
          ----------------

     The bit model defines the interpretation of an integer value as a
     sequence of bits.  For more information on the bit model, see the
     MODELS(3I) man page.

EXAMPLES
     IOR (1, 3) has the value 3.
