新手中的新手。用BILOG软件想做DIF分析。照猫画虎一步步完成后，根本不执行run. 实在不知道原因在哪？
附件是原始数据。
烦请大家帮忙解答一下……
多谢多谢！

>GLOBAL DFName = 'H:\1.dat',
        NPArm = 1,
        NTEst = 4,
        LOGistic,
        SAVe;
>SAVE PARm = '1.PAR',
      DIF = '1.DIF';
>LENGTH NITems = (5(0)4),
        NVAriant = (0(0)4);
>INPUT NTOtal = 20,
       NIDchar = 4,
       NGRoup = 2,
       KFName = 'H:\key.dat',
       DIF;
>ITEMS ;
>TEST1 TNAme = 'TEST0001',
       INUmber = (1(1)5);
>TEST2 TNAme = 'TEST0002',
       INUmber = (6(1)10);
>TEST3 TNAme = 'TEST0003',
       INUmber = (11(1)15);
>TEST4 TNAme = 'TEST0004',
       INUmber = (16(1)20);
>GROUP1 GNAme = 'GROUP001',
        LENgth = 20,
        INUmbers = (1(1)20);
>GROUP2 GNAme = 'GROUP002',
        LENgth = 20,
        INUmbers = (1(1)20);
(4A1, 1X, I1, 5X, 41A1)
>CALIB CYCles = 15,
       CRIt = 0.0500,
       SELect = (1(0)4);
>SCORE NQPt = (0(0)4);


另外，就是最普通的item analysis为什么也不能执行到底呢？总是说not successful. why??????
语句如下：

>GLOBAL DFName = 'H:\1.dat',
        NPArm = 2,
        NTEst = 4;
>LENGTH NITems = (5(0)4),
        NVAriant = (0(0)4);
>INPUT NTOtal = 20,
       NIDchar = 4,
       KFName = 'H:\key.dat';
>ITEMS ;
>TEST1 TNAme = 'TEST0001',
       INUmber = (1(1)5);
>TEST2 TNAme = 'TEST0002',
       INUmber = (6(1)10);
>TEST3 TNAme = 'TEST0003',
       INUmber = (11(1)15);
>TEST4 TNAme = 'TEST0004',
       INUmber = (16(1)20);
(4A1, 7X, 41A1)
>CALIB SELect = (1(0)4),
       ACCel = 1.0000;
>SCORE NQPt = (0(0)4);
