SdaiAggr operand2,
SdaiLogical *result);
Implements the Express Aggregate Instance Comparison> operation as defined in section 12.2.2.1 Aggregate instance comparison; in ISO 10303-11:1994(E) : The EXPRESS Language Reference Manual. This operation is only applicable to aggregates in data models. The actual data models must be open before this function can be successfully performed.
Arguments
| Type | Name | Comment |
| SdaiAggr | operand1 | A numeric aggregateID that uniquely identifies the aggregate instance used as operand1 (left operand) in the aggregate instance compare operation. |
| SdaiAggr | operand2 | A numeric aggregateID that uniquely identifies the aggregate instance used as operand2 (right operand) in the aggregate instance compare operation. |
| SdaiLogical | result | Address of a variable that will receive the result of the aggregate instance compare operation. |

break;
case sdaiFALSE:
. . . /* The two aggregates are not instance value equal */
