OR — Bitwise logical OR#

OR(I, J)#

Bitwise logical OR.

Parameters

  • I – The type shall be either a scalar INTEGER type or a scalar LOGICAL type or a boz-literal-constant.

  • J – The type shall be the same as the type of I or a boz-literal-constant. I and J shall not both be boz-literal-constants. If either I and J is a boz-literal-constant, then the other argument must be a scalar INTEGER.

Returns

The return type is either a scalar INTEGER or a scalar LOGICAL. If the kind type parameters differ, then the smaller kind type is implicitly converted to larger kind, and the return has the larger kind. A boz-literal-constant is converted to an INTEGER with the kind type parameter of the other argument as-if a call to INT occurred.

Standard:

GNU extension

Class:

Function

Syntax:
RESULT = OR(I, J)
Example:
PROGRAM test_or
  LOGICAL :: T = .TRUE., F = .FALSE.
  INTEGER :: a, b
  DATA a / Z'F' /, b / Z'3' /

  WRITE (*,*) OR(T, T), OR(T, F), OR(F, T), OR(F, F)
  WRITE (*,*) OR(a, b)
END PROGRAM
