DESCRIP
For each Level
(
) dimension there will be
DIMSPEC
.DUPNUM DESCRIP records.
The descriptor
records may be in any order, but it is recommended
that they be in order of
Level 1: 1 through
[4]DIMSPEC1.DUPNUM,
followed by Level 2: 1 through
[4]DIMSPEC2.DUPNUM,
followed by Level 3: 1 through
[4]DIMSPEC3.DUPNUM.
The information in this record type is considered to be an alternative
description of the dimension it parallels.
There must be a DESCVAL record for each
DESCRIP record, to specify the
grid points along that dimension. An
optional DESCSUP record may be
present if additional information is required.
- name
-
- RECTYPE
-
- I
- is the record type code = 34
- LEVEL
-
- I
- is the dimensional level
- DEXSORT
-
- I
- NDEX
- (bits 0-15) is an index that corresponds to the
same field in the associated DIMSPEC1,
DIMSPEC2, or DIMSPEC3 record.
Counting begins at 0 or 1 as specified in
TEST.SPECB.IDXSTART.
See the discussion in Section 2.3.2
- RECSORT
- (bits 16-31) is an index that corresponds to the
same field in the associated DIMSPEC1,
DIMSPEC2, or DIMSPEC3 record.
See the discussion in Section 2.3.2
- DESSUP
-
- I
- is the number of floating-point values in the SVALS field of
the following DESCSUP record. If zero, then there is no DESCSUP record
for this dimension
- DESFMT
-
- I
- is the descriptor format code. This code is explained in
Section A.1.1
- DESTYPE
-
- I
- is the quantity code for the physical quantity that the
dimension represents. This code is explained in Section A.1.3
- UNITS
-
- I
- is the units code for the physical quantity that the dimension
represents. This code is explained in Section A.1.1
- STORG
-
- I
- specifies how the values of the descriptor are stored in the
DESCVAL record which follows. The possible values are:
-
-
-
0 |
= |
an explicit array of [4]DESCRIP1.GPTNUM,
DIMSPEC2.GPTNUM, or
DESCRIP3.GPTNUM values |
1 |
= |
an implicit specification consisting of a (low-value, interval) pair |
2 |
= |
an implicit specification consisting of a (low-value, high-value) pair |
- DINDEX
-
- I
- index serving as an identifier
(within a given DEXSORT and
LEVEL)
of the Descgroup record group begun by this record.
Values must be greater than zero. (A value of zero would imply that this
is a DESCRIP1, DESCRIP2,
or DESCRIP3 record instead of DESCRIP.)
- RESERVE0
