Subject: Write to file

Hi,

I'm trying to write to a new file, wich I'm creating by

file=File.new('file.txt', 'w')

This works fine so far, the file is created in my working folder and
contains the text I'm putting in.

Now I want the user to input the filename, so I modified my source code
like this:


print "Please insert file name: "

file_name=gets

file=File.new(file_name+'.txt', 'w')

Running the Programm and inputting 'test' (without the ''), I get the
following Error:

..\rubyfile.rb:116:in `initialize': Invalid argument - test
(Errno::EINVAL)
.txt
        from ..\rubyfile.rb:116:in `new'
        from ..\rubyfile.rb:116

I have no idea, what's going wrong... Since file_name is a string,
file_name+'.txt' ought to be a string too, and thus a valid argument for
the initializer method of File, or not?

Sorry, if my question is dumb, I'm a total noob with ruby...

Thanks for any help!
