|---|
| 36 | C Most of the decoded information for the selected GRIB field |

| 37 | C is returned in a derived type variable, gfld. |
|---|
| 38 | C Gfld is of type gribfield, which is defined |
|---|
| 39 | C in module grib_mod, so users of this routine will need to include |
|---|
| 40 | C the line "USE GRIB_MOD" in their calling routine. Each component of the |
|---|
| 41 | C gribfield type is described in the OUTPUT ARGUMENT LIST section below. |

| 261 | C REMARKS: |
|---|
| 262 | C THIS SUBPROGRAM IS INTENDED FOR PRIVATE USE BY GETGB2 ROUTINES ONLY. |
|---|
| 263 | C |
|---|
| 264 | C Note that derived type gribfield contains pointers to many |
|---|
| 265 | C arrays of data. The memory for these arrays is allocated |
|---|
| 266 | C when the values in the arrays are set, to help minimize |
|---|
| 267 | C problems with array overloading. Because of this users |
|---|
| 268 | C are encouraged to free up this memory, when it is no longer |
|---|
| 269 | C needed, by an explicit call to subroutine gf_free. |
