Starting with gfortran-8 :
$ cat z1.f90
program p
character(3), parameter :: a(4) = 'abc'
integer, parameter :: b(1) = minloc(a)
integer, parameter :: c = minloc(a, dim=1)
end
$ cat z2.f90
program p
character(3), parameter :: a(4) = 'abc'
integer, parameter :: b(1) = maxloc(a)
integer, parameter :: c = maxloc(a, dim=1)
end
