The following GRIBEX Fortran interface is no longer present in the GRIB API. You will have seen from the GRIB API In the ecCodes Fortran 90 interface that the information contained in the GRIB message can be accessed through alphanumeric keys.
In your Fortran code, you will have to explicitly name the keys that you are using. The tables below will help you find the key names corresponding to the "old" GRIB1 header section elements.
These tables include the GRIB API ecCodes Coded key names and also Recommended GRIB API key names. You should use the latter.

Find the corresponding ecCodes key names to the elements in the GRIBEX ksec0(*), ..., ksec4(*), psec2(*),...psec4(*) header sections. Use the links shown above

Try to use the "recommended" keys, i.e. keys that are valid for both GRIB -edition 1 and GRIB -edition 2 (for instance "dataDate" instead of "YearOfCentury", "month", "day").
