PAKSPEC

This record type specifies how the data are packed. The data object will contain OBJDESC.NPACKS records of this record type, and no records of this type if OBJDESC.NPACKS is zero. The records will be processed in order of their RECSORT fields. There can be an overlap of grid points specified in the START and END fields, but this use is strongly discouraged.

RECTYPE

I

is the record type code = 60

RECSORT

I

is the index for sorting the records. Lower valued records will be processed before higher valued records. See the discussion in Section 2.3.2

START

I*

is an array of Level 0, Level 1, and Level 2 dimension grid points over which this record begins to apply. The first OBJDESC.NDIM0 elements correspond to the Level 0 dimensions. The middle OBJDESC.NDIM1 elements correspond to the Level 1 dimensions. The last OBJDESC.NDIM2 elements correspond to the Level 2 dimensions. Counting begins at 0 or 1 as specified in TEST.SPECB.IDXSTART. See the discussion in Section 2.3.2

END

I*

is an array of Level 0, Level 1, and Level 2 dimension grid points over which this record stops applying. The first OBJDESC.NDIM0 elements correspond to the Level 0 dimensions. The middle OBJDESC.NDIM1 elements correspond to the Level 1 dimensions. The last OBJDESC.NDIM2 elements correspond to the Level 2 dimensions. A value of -1 indicates the last grid point of that dimension. Counting begins at 0 or 1 as specified in TEST.SPECB.IDXSTART. See the discussion in Section 2.3.2

CODE

I

is the packing code. This code is explained in Section A.1.5

RESERVE0

I

is reserved for future expansion

RESERVE1

I

is reserved for future expansion

DPAKFMT

I

is the format of the packed data values in the PAKDAT.VALS field. (After unpacking, the data will have the format as specified in DESCRIP0.DATFMT.) See Section A.1.1

PAKNUM

I

is the number of values in the PAKVAL.INFO field. PAKNUM should match the number of values implied by the CODE field. If there are no values, then this should be set to zero, and there will be no PAKFORM record and no PAKVAL.INFO field
