Issues with range2loop expansion of string with (1:1)

[sergisiso]

Intel compiler doesn´t accept:

do idx = 1, 1, 1
    cdltmp(idx) = ...

as a range2loop expansion of:

CHARACTER(LEN = ilenlong) :: cdltmp
cdltmp(1:1) = ACHAR(IACHAR(cdltmp(1 : 1)) + 32)

It produces:

NEMOGCM_V40/cfgs/SPITZ12_openmp_cpu/WORK/obs_fbm.f90(1024): error #6410: This name has not been declared as an array or a function.   [CDLTMP]

I think the validate method should reject this as a character sub-string does not imply a loop?

#2511 Fixes the issue when the array.datatype is an array of character type. But I will not close this issue yet because it is still a problem when the type is Unresolved or Unknown as is the case with CHARACTER(LEN = ilenlong) :: cdltmp or imported symbols
