.PP
This subroutine packs up a data field using a complex packing algorithm as defined in the GRIB2 documention\&. It supports GRIB2 complex packing templates with or without spatial differences (i\&.e\&. DRTs 5\&.2 and 5\&.3)\&. It also fills in GRIB2 Data Representation Template 5\&.2 or 5\&.3 with the appropriate values\&.
.PP
\fBParameters\fP
