I could only come up with the little piece of code I wrote below and it's not even working. I believe the problem is on line 13 but I'm not so sure.
I would appreciate if you could tell me where the problem is and point me to the right direction.
Also, if you know a more cunning way to do what I intend please do tell me.

Thanks,

The idea was evaluate every character of a text file (say a text of a newspaper for example) and separate words. Valid words would be strings of char from 'a' to 'z' only.
At the time a space is encountered I'd make a new line. I fact if I modify the while loop and use the following code instead:


the programme does pretty much what I want but I still don't know what to do the commas, etc (that is every thing having an ascii code outside the a-z range)
