### 9.16 `AND`

— Bitwise logical AND

*Description*:Bitwise logical

`AND`

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

*Standard*:GNU extension

*Class*:Function

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

*Arguments*:`I`The type shall be either a scalar `INTEGER`

type or a scalar`LOGICAL`

type.`J`The type shall be the same as the type of `I`.*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.*Example*:PROGRAM test_and LOGICAL :: T = .TRUE., F = .FALSE. INTEGER :: a, b DATA a / Z'F' /, b / Z'3' / WRITE (*,*) AND(T, T), AND(T, F), AND(F, T), AND(F, F) WRITE (*,*) AND(a, b) END PROGRAM
