DESOBJ – Objective Selection

Only one DESOBJ card can be present.
For global DRESP1 responses (responses which are not subcase dependent) or DRESP2 responses containing either DRESP1L data or global DRESP1 responses, the DESOBJ data must be above the first SUBCASE statement.
If the DESOBJ data references responses that are subcase specific, then the DESOBJ statement must be within the appropriate subcase definition and the subcase must be of the appropriate type.
