As such 13 * it is invalid, since octal escapes may only run from '\0' to '\377'. But 14 * the lexer should interpret this as '\40' + '0' instead, and throw no error. 15 * 16 */ 17 //----------------------------------------------------------------------------- 18 var UBound = 0; 19 var BUGNUMBER = 177314; 20 var summary = "'\\" + "400' should lex as a 2-digit octal escape + '0'"; 21 var status = ''; 22 var statusitems = []; 23 var actual = ''; 24 var actualvalues = []; 25 var expect= ''; 26 var expectedvalues = []; 27 28 29 // the last valid octal escape is '\377', which should equal hex escape '\xFF' 30 status = inSection(1); 31 actual = '\377'; 32 expect = '\xFF'; 33 addThis(); 34 35 // now exercise the lexer by going one higher in the last digit 36 status = inSection(2); 37 actual = '\378'; 38 expect = '\37' + '8'; 39 addThis(); 40 41 // trickier: 400 is a valid octal number, but '\400' isn't a valid octal escape 42 status = inSection(3); 43 actual = '\400'; 44 expect = '\40' + '0'; 45 addThis(); 46 47 48 49 //----------------------------------------------------------------------------- 50 test(); 51 //----------------------------------------------------------------------------- 52 53 54 55 function addThis() 56 { 57 statusitems[UBound] = status; 58 actualvalues[UBound] = actual; 59 expectedvalues[UBound] = expect; 60 UBound++; 61 } 62 63 64 function test() 65 { 66 printBugNumber(BUGNUMBER); 67 printStatus(summary); 68 69 for (var i=0; i<UBound; i++) 70 { 71 reportCompare(expectedvalues[i], actualvalues[i], statusitems[i]); 72 } 73 }
