This is only standard conform after changing dfloat() to real(..., kind(0d0))
and after changing
call getrelval('sib', 'mea', 'test', 4, 1, MISS, work, 0)
into
call getrelval('sib', 'mea', 'test ', 4, 1, MISS, work, 0)
With these changes it is Fortran 2003 standard conform and also compiles with
NAG f95

integer, dimension(dataset%maxsiz) :: nobs
integer, dimension(dataset%maxsiz, MAXREC) :: relid
type (ped_data) :: dataset
I think gfortran rightly rejects the file though the error message should be
improved.
NAG f95 writes:
Error: z.f90, line 253: Implicit type for DATASET
detected at [EMAIL PROTECTED]
Error: z.f90, line 253: DATASET is not of derived type
detected at [EMAIL PROTECTED]
Error: z.f90, line 256: Symbol DATASET has already been implicitly typed
detected at ::@DATASET
ifort is also better:
fortcom: Error: z.f90, line 253: The structure-name is invalid or is missing.
integer, dimension(dataset%maxsiz) :: nobs
gfortran:
Error: Expected another dimension in array declaration at (1)
and later:
Error: Symbol 'nobs' at (1) has no IMPLICIT type
If I'm not mistaken, the relevant part of the standard is:
"A variable within a specification expression shall have its type
and type parameters, if any, specified by a previous declaration
in the same scoping unit, by the implicit typing rules in effect
for the scoping unit, or by host or use association. If a variable
in a specification expression is typed by the implicit typing rules,
its appearance in any subsequent type declaration statement shall
confirm the implied type and type parameters."
