这样的控制语句要如何写？请教!

LR8.0自带的sample中的飞机订票系统中，飞机的出发点与到达点，一般情况下应该是不相同的，比如说从上海出发，那到达地一般不会是上海，而是别的城市。
那在订飞机票时如何优化脚本来控制这一点呢。
以下我的脚本：
Action()
{
char city[30];
char city1[30];

lr_start_transaction("reserver");

web_set_max_html_param_len("10240");
// [WCSPARAM WCSParam_Diff2 10 returnDate] Parameter {WCSParam_Diff2} created by Correlation Studio
web_reg_save_param( "WCSParam_Diff2", "LB= NAME=\"", "RB=\"", "Ord=6", "Search=Body", "RelFrameId=1.2", LAST );
// [WCSPARAM WCSParam_Diff3 10 12/14/2006] Parameter {WCSParam_Diff3} created by Correlation Studio
web_reg_save_param( "WCSParam_Diff3", "LB= VALUE=\"", "RB=\"", "Ord=12", "Search=Body", "RelFrameId=1.2", LAST );
// [WCSPARAM WCSParam_Diff4 10 12/15/2006] Parameter {WCSParam_Diff4} created by Correlation Studio
web_reg_save_param( "WCSParam_Diff4", "LB= VALUE=\"", "RB=\"", "Ord=25", "Search=Body", "RelFrameId=1.2", LAST );

if (strcmp(depart,arrive) == 0)
     
      {

      }

以上的脚本并没能保证出发点与到达点不一样。
分析如下：
1：depart取了‘上海’，如果arrive也取了‘上海’，这时候脚本继续运行，此时“"Name=roundtrip", "Value=<OFF>", ENDITEM,”此句中value=off
控制语句没能起到作用，不知道是不是语句放的位置不对？
2：还有一种想法，因为当value=on时，此订票才是有效的，有什么办法可以在发现出发点与到达点相同时就把这个value的值置为on呢？
3：另外 或者发现相同时，先把这条订票删除再重新订票而不是只是重新选择到达点(arrive)?

没太看明白,:(

好像这次CPC考试就有一个这样的题目,呜呜,没弄出来.

是吗？你也要参加这次的考试？那你已经通过SP考试了？有何收获
