atomic_or in Fortran Wiki

## Description
`atomic_or(atom, value)` atomically defines `atom` with the bitwise
`or` between the values of `atom` and `value`. When `stat` is present
and the invocation was successful, it is assigned the value 0. If it
is present and the invocation has failed, it is assigned a positive
value; in particular, for a coindexed `atom`, if the remote image has
stopped, it is assigned the value of `iso_fortran_env`'s
`stat_stopped_image` and if the remote image has failed, the value
`stat_failed_image`.
## Standard
[[TS 18508]] or later
## Class
Atomic subroutine
## Syntax
~~~~~~~~~~~~~~~~~~ {: lang=fortran }
call atomic_or(atom, value [, stat])
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
## Arguments
- `atom` - Scalar coarray or coindexed variable of integer
 type with `atomic_int_kind` kind.
- `value` - Scalar of the same type as `atom`. If the kind
 is different, the value is converted to the kind of `atom`.
- `stat` - (optional) Scalar default-kind integer variable.
## Example
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ {: lang=fortran }
program atomic
 use iso_fortran_env
 integer(atomic_int_kind) :: atom[*]
 call atomic_or(atom[1], int(b'10100011101'))
end program atomic
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
