DIMSPEC1

This record type specifies the Level 1 dimensions of the data object. There can be several DESCRIP1 records for each Level 1 dimension. The field arrays are OBJDESC.NDIM1 elements in length.

INDEX

I*

is the relative index pointer for the Level 1 dimensions. The values in this field are pointers that map the ordering of the DESCRIP1 records into the actual data array index order. Counting begins with 0 or 1 as specified in TEST.SPECB.IDXSTART. See the discussion in Section 2.3.2

DESNUM

I*

is the number of DESCRIP1 records used to describe this dimension. The user can specify a different number of Level 1 dimension grid points along various Level 2 dimensions; these different Level 1 dimension definitions require different DESCRIP1 records, whose number is given here. Note, however, these differing Level 1 dimensions must be defined over non-overlapping ranges of Level 2 dimensions. DESNUM values must be greater than zero
