%LOC as an rvalue (The GNU Fortran Compiler)

#### 5.1.28 %LOC as an rvalue ¶

Normally `%LOC` is allowed only in parameter lists. However the intrinsic function `LOC` does the same thing, and is usable as the right-hand-side of assignments. For compatibility, GNU Fortran supports the use of `%LOC` as an alias for the builtin `LOC` with `-std=legacy`. With this feature enabled the following two examples are equivalent:

    integer :: i, l
    l = %loc(i)
    call sub(l)

    integer :: i
    call sub(%loc(i))
