1，需要从网页下载文件，
2, 文件比较多, 几十个, 文件名有规律 (A001-A020.ext,B001-B020.ext, 但数量并不
确定)
3，周一至周六下载
4, 下载到特定目录, 目录名就定为当日日期
最好比较自动, 你们有什么建议？
我以前会 C，汇编，还有其他语言，编程没有什么问题，但是多年没用，

Data-Check is considering two capital structures. The key information is
shown in the following table. Assume a 40% tax rate.
Source of capital Structure A Structure B
Long-term debt $100,000 at 16% coupon rate $200,000 at 17%
coupon rate
Common stock 4,000 shares 2,000 shares
a. Calculate two EBIT-EPS coordinates for each of the structures by
selecting any two EBIT values and finding their associated EPS.
c. Indicate over what EBIT range

shell+wget就够了。
复杂点python或者java吧。

Structure A Structure B
interest expense 16,000 34,000
A's EPS = (1-40%)(EBIT - 16000)/4000
B's EPS = (1-40%)(EBIT - 34000)/2000
EPS of A and B will be the same when EBIT reaches 52000, B's EPS will exceed
A's after that.
preferred.
so far I only had two lectures in corp finance. Looks like we should try to
maximize firm's total value when considering which structure is preferred. I
think we should choose B when EBIT>34,000 to ma
