Thanks I actually have done that but couldn't understand how to use them.
Can you give me an example on a function that reads a file and in case the
file is not found you throw a string like "File not found" or so??

main = do

case v of

I am working on a small program which writes a text
file but I need this file to be in UNIX format and as it is a Windows program I
am compiling it, the output file tends to be in DSO format. Is there anyway that
I can force it to create the file in UNIX format???
Best Regards

I am not an expert on the subject, but ... maybe you just have to use a
string constant
