### 9.212 `OR`

— Bitwise logical OR

*Description*:Bitwise logical

`OR`

.This intrinsic routine is provided for backwards compatibility with GNU Fortran 77. For integer arguments, programmers should consider the use of the IOR intrinsic defined by the Fortran standard.

*Standard*:GNU extension

*Class*:Function

*Syntax*:`RESULT = OR(I, J)`

*Arguments*:`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`

.*Return value*: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.*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
