Hi, Mac

My program is not that complex though.
The file has format like this:

C:\Documents and Settings\cheynel\Desktop\p001hello.txt,puts
C:\Documents and Settings\cheynel\Desktop\hello.rb,print
C:\Documents and Settings\cheynel\Desktop\04.rb,Thank
C:\Documents and Settings\cheynel\Desktop\read.rb,print
C:\Documents and Settings\cheynel\Desktop\class.rb,class
C:\Documents and Settings\cheynel\Desktop\reg.rb,cheyne

So, basically, each line has 2 arguments,which is seperated by ","

the first argument is the location of the test fils, and the second one 
is the key word to match corresponding the file. such as, "puts" is need 
to be found in poo1hello.txt, not need to be found in hello.

Well, the problem is solved, I found the string read in from a file will 
automatically attached with something, which I'm quite sure if it is 
newline. but use str.chop! will solve it.

Anyway, Thank you for your reply
