| |
| 11.13.2 Compound assignment ( op= ) |
| |
| The production AssignmentExpression : |
| LeftHandSideExpression @ = AssignmentExpression, where @ represents one of |
| the operators indicated above, is evaluated as follows: |
| |
| 1. Evaluate LeftHandSideExpression. |
| 2. Call GetValue(Result(1)). |
| 3. Evaluate AssignmentExpression. |
| 4. Call GetValue(Result(3)). |
| 5. Apply operator @ to Result(2) and Result(4). |
| 6. Call PutValue(Result(1), Result(5)). |
| 7. Return Result(5). |
