主题：请问DEBUGFILE2和DEBUGFILE

按照：debugfile2('d:\test.txt','ma=%.2f',ma(c,5),1)

在1分钟周期下，打印出来的文件是这样的：

2014-02-21 10:28:05.444    ma=-1.#R
2014-02-21 10:28:05.445    ma=-1.#R

2014-02-21 10:28:05.460    ma=2183.72
2014-02-21 10:28:05.460    ma=2183.60
2014-02-21 10:28:05.461    ma=2183.24
2014-02-21 10:28:05.462    ma=2182.72

好像不是每个周期结束才打印，请问是什么问题？
