测试脚本：
Action()
{
int i=0;
//循环10次 ，输出变量的值
for(i;i<=10;i++){
lr_output_message("%s",lr_eval_string("{parameterized}"));
}
return 0;
}
参数列表个数为5：
参数化配置之如何取值（select next row）：
1、select next row：Sequential（按顺序选择下一行，当递归到最后一个参数后，从第一个参数开始重新递归）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value2
Action.c(7): Value3
Action.c(7): Value4
Action.c(7): Value5
Action.c(7): Value1
Action.c(7): Value2
Action.c(7): Value3
Action.c(7): Value4
Action.c(7): Value5
Ending action Action.
Ending iteration 1.
2、select next row：Random（随机值，从参数列表中随机选取值）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value1
Action.c(7): Value3
Action.c(7): Value5

3、select next row：Unique（唯一值，按顺序选择下一行，当递归到最后一个参数后，LoadRunner直接报错）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value2
Action.c(7): Value3
Action.c(7): Value4
Action.c(7): Value5
Action.c(7): Error: Parameter ‘parameterized‘: No more unique values for this parameter in table ‘parameterized.dat‘ [unique range is 1-5].The parameter continues with last value of the range according to "When Out Of Values" policy.

Ending iteration 1
参数化配置之何时取值（update value on）：
1、update value on：each iteration（每次迭代的时候取值，在同一个迭代中，无论读多少次，获得的都是同一个参数值）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value1
Action.c(7): Value1

Starting iteration 2.
Starting action Action.
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Action.c(7): Value2
Ending action Action.
Ending iteration 2.
2、update value on：each occurrence（只要取一次，就要新的）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value2
Action.c(7): Value3
Action.c(7): Value4
Action.c(7): Value5

Action.c(7): Value2
Action.c(7): Value3
Action.c(7): Value4
Action.c(7): Value5
Ending action Action.
Ending iteration 2.
3、update value on：once（在所有循环中都使用同一个值）
代码执行结果：
Starting iteration 1.
Starting action Action.
Action.c(7): Value1
Action.c(7): Value1
Action.c(7): Value1
Action.c(7): Value1
