Evaluate the Expression. michael@0: 2. Call GetValue(Result(1)). michael@0: 3. Call ToObject(Result(2)). michael@0: 4. Let C be "normal completion". michael@0: 5. Get the name of the next property of Result(3) that doesn't have the michael@0: DontEnum attribute. If there is no such property, go to step 14. michael@0: 6. Evaluate the LeftHandSideExpression ( it may be evaluated repeatedly). michael@0: 7. Call PutValue(Result(6), Result(5)). PutValue( V, W ): michael@0: 1. If Type(V) is not Reference, generate a runtime error. michael@0: 2. Call GetBase(V). michael@0: 3. If Result(2) is null, go to step 6. michael@0: 4. Call the [[Put]] method of Result(2), passing GetPropertyName(V) michael@0: for the property name and W for the value. michael@0: 5. Return. michael@0: 6. Call the [[Put]] method for the global object, passing michael@0: GetPropertyName(V) for the property name and W for the value. michael@0: 7. Return. michael@0: 8. Evaluate Statement. michael@0: 9. If Result(8) is a value completion, change C to be "normal completion michael@0: after value V" where V is the value carried by Result(8). michael@0: 10. If Result(8) is a break completion, go to step 14. michael@0: 11. If Result(8) is a continue completion, go to step 5. michael@0: 12. If Result(8) is a return completion, return Result(8). michael@0: 13. Go to step 5. michael@0: 14.
