SDisdimval_bwcomp/sfisdmvc

intn SDisdimval_bwcomp(int32 dim_id)
dim_id

IN:

Dimension identifier returned from SDgetdimid

Purpose

Determines whether the specified dimension will have the old and new representations or the new representation only.

Return value

Returns SD_DIMVAL_BW_COMP (or 1) if backward compatible, SD_DIMVAL_BW_INCOMP (or 0) if incompatible, FAIL (or -1) if error.

Description

SDstart reads dimension records into memory. The compatiblity mode of each dimesion is decided by the existance of the dimension vdata of class "DimVal0.0" in the dimension vgroup for that dimension.

If "DimVal0.0" vdata doesn't exist in that dimension vgroup, it will be flagged as backward-incompatible. The compatibility mode can be changed by calls to SDsetdimval_comp at any time between the calls to SDstart and SDend.
