VEE Pro中的计数使用情况

对不起我的入门级问题。我想做的是：将复制数据逐个复制（使用For Count）从a.txt复制到b.txt，在复制过程开始时，添加开始时间（使用
now（）函数）;而在最后，添加结束时间（使用now（）函数）问题描述：对于流程图，1）Start2）将当前开始时间写入b.txt3）设置循环（For Count），
将a.txt一个接一个地复制到b.txt4）将当前结束时间写入b.txt我希望记录一个开始和一个结束时间，但是，我得到的是一个开始但是几个（数字等于For Count number）结束时间
记录，我想这个问题出现在For Count部分，其中结束时间记录也包含在循环中。
有没有人遇到与For Count类似的问题？
非常感谢您的帮助。

  Sorry for my entry-level question.

What I wanted to do is:
Copy the txt data one by one (using For Count) from a.txt to b.txt,
at the beginning of the copy process, add the starting time (using now() function);
while in the end, add the ending time (using now() function)

Problem Description:
for the flow chart,
1)Start
2)write current start time to b.txt
3)set loop (For Count), copy a.txt to b.txt one by one
4)write current end time to b.txt
I wanted to have one start and one end time recorded, however, what I got is
one start but several (number equals to For Count number) end time record,
I guess the problem is in the For Count part, where the end time recording is
also included in the loop.

Has anyone encountered similar problems with For Count? Really appreciate your help.
