Synopsis:

RESULT = IOR(I, J)

Description:

IOR returns the bitwise Boolean inclusive-OR of I and J.

Class:

Elemental function

Arguments:

I	The type shall be INTEGER, UNSIGNED or a boz-literal-constant.
J	The type shall be the same type as I with the same kind type parameter or a boz-literal-constant. I and J shall not both be boz-literal-constants.

Return value:

The return type is INTEGER with the kind type parameter of the arguments. A boz-literal-constant is converted to an INTEGER or UNSIGNED with the kind type parameter of the other argument as-if a call to INT or UINT, respectively, occurred.

Specific names:

Name	Argument	Return type	Standard

BIOR(A)	INTEGER(1) A	INTEGER(1)	GNU extension
IIOR(A)	INTEGER(2) A	INTEGER(2)	GNU extension
JIOR(A)	INTEGER(4) A	INTEGER(4)	GNU extension
KIOR(A)	INTEGER(8) A	INTEGER(8)	GNU extension
