| 10 Description: | |
| 11 | |
| 12 *= /= %= += -= <<= >>= >>>= &= ^= |= | |
| 13 | |
| 14 11.13.2 Compound assignment ( op= ) | |
| 15 | |
| 16 The production AssignmentExpression : | |
| 17 LeftHandSideExpression @ = AssignmentExpression, where @ represents one of | |
| 18 the operators indicated above, is evaluated as follows: | |
| 19 | |
| 20 1. Evaluate LeftHandSideExpression. | |
| 21 2. Call GetValue(Result(1)). | |
| 22 3. Evaluate AssignmentExpression. | |
| 23 4. Call GetValue(Result(3)). | |
| 24 5. Apply operator @ to Result(2) and Result(4). | |
| 25 6. Call PutValue(Result(1), Result(5)). | |
| 26 7. Return Result(5). | |
