Function/Subroutine Documentation

compack()

subroutine compack	(	real, dimension(ndpts), intent(in)	fld,
		integer, intent(in)	ndpts,
		integer, intent(in)	idrsnum,
		integer, dimension(*), intent(inout)	idrstmpl,
		character(len=1), dimension(*), intent(out)	cpack,
		integer, intent(out)	lcpack
	)

This subroutine supports GRIB2 complex packing templates with or without spatial differences, Data Representation Templates (DRT) [GRIB2 - DATA REPRESENTATION TEMPLATE 5.2 - Grid point data - complex packing](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-2.shtml) and [GRIB2 - DATA REPRESENTATION TEMPLATE 5.3 - Grid point data - complex packing and spatial differencing](https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-3.shtml).

It also fills in GRIB2 Data Representation Template 5.2 or 5.3 with the appropriate values.

Parameters

[in]	fld	The data values to pack.
[in]	ndpts	The number of data values in array fld.
[in]	idrsnum	Data Representation Template number - must equal 2 or 3.
[in,out]	idrstmpl	The array of values for Data Representation Template 5.2 or 5.3. 1 Reference value - ignored on input 2 Binary Scale Factor 3 Decimal Scale Factor 7 Missing value management 8 Primary missing value 9 Secondary missing value 17 Order of Spatial Differencing (1 or 2)
[out]	cpack	The packed data field (character*1 array).
[out]	lcpack	length of packed field cpack.
