Evaluate MemberExpression. 31 2. Call GetValue(Result(1)). 32 3. Call ToNumber(Result(2)). 33 4. Subtract the value 1 from Result(3), using the same rules as for the - 34 operator (section 0). 35 5. Call PutValue(Result(1), Result(4)). 36 6. Return Result(3). 37 38 Author: christine (at) netscape.com 39 Date: 12 november 1997 40 */ 41 var SECTION = "11.3.2"; 42 var VERSION = "ECMA_1"; 43 startTest(); 44 var testcases = getTestCases(); 45 46 writeHeaderToLog( SECTION + " Postfix decrement operator"); 47 test(); 48 49 function test() { 50 for ( tc=0; tc < testcases.length; tc++ ) { 51 testcases[tc].passed = writeTestCaseResult( 52 testcases[tc].expect, 53 testcases[tc].actual, 54 testcases[tc].description +" = "+ 55 testcases[tc].actual ); 56 57 testcases[tc].reason += ( testcases[tc].passed ) ?
