参数化的问题？【已解决】

wistaria

使用socket协议
Action:
lr_save_string(num,"{Numchanged}"); //修改参数值, Numchanged原值= 8001    num = \x1a\xa8

lrs_send("socket1", "buf0", LrsLastArg);//Numchanged是"buf0"中的参数，修改参数值在send之前

Replay log:
Action.c(31): Notify: Parameter Substitution: parameter "Numchanged" =  "8001"
Action.c(39): Notify: Saving Parameter "{Numchanged} = \x1a\xa8"           //提示参数修改成功

可是send出去的数据参数还是8001，未修改！为何？

Action()

        char num[5];
         memset(num);           
        StringTocompressAscii(num,sizeof(num) - 1,lr_eval_string("{NumChange}"),strlen(lr_eval_string("{NumChange}")));//自己写的DLL封装函数，
        lr_save_string(num,"{NumChange}");
        lr_output_message ("NumChange is %s",lr_eval_string("{NumChange}"));
        lrs_send("socket1", "buf0", LrsLastArg);
        lr_output_message ("NumChange is %s",lr_eval_string("{NumChange}"));
        return 0;
}

wistaria

lr_save_string(num,"{NumChange}");

改写为
lr_save_string(num,"NumChange");

trapezia

lr_save_string是个很怪异的函数。

不错呀,顶了呀
