		integer, intent(in)	lcgrib,
		integer, intent(inout)	iofst,
		integer, intent(out)	ndpts,
		integer, intent(out)	idrsnum,

This subroutine unpacks Section 5 (Data Representation Section) starting at octet 6 of that Section.

PROGRAM HISTORY LOG:

2000-05-26 Stephen Gilbert Initial development.
2002-01-24 Stephen Gilbert Changed to dynamically allocate arrays and to pass pointers to those arrays through the argument list.

Parameters

[in]	cgrib	Character array that contains the GRIB2 message.
[in]	lcgrib	Length (in bytes) of GRIB message array cgrib.
[in,out]	iofst	Bit offset of the beginning/end(returned) of Section 5.
[out]	ndpts	Number of data points unpacked and returned.
[out]	idrsnum	Data Representation Template Number (Code Table 5.0).
[out]	idrstmpl	Contains the data values for the specified Data Representation Template (N=idrsnum). Each element of this integer array contains an entry (in the order specified) of Product Defintion Template 5.N A safe dimension for this array can be obtained in advance from maxvals(6), which is returned from subroutine gribinfo.
[out]	mapdrslen	Number of elements in idrstmpl. i.e. number of entries in Data Representation Template 5.N (N=idrsnum).
[out]	ierr	Error return code. 0 no error. 6 memory allocation error. 7 "GRIB" message contains an undefined Grid Definition Template.
