Subject: Re: Windows and Ruby - Not very good friends?

Gents,
First, thank you all for your time and quick responses.  I am beginning 
to see why people are flocking to ruby besides the language itself and 
the RoR framework.  It is the wonderful community help eco-system 
surrounding it.  May be with your help, I can come up to speed and start 
helping others.

Second, you are right.  I am running it from SciTe.  In Linux world, I 
am more comfortable at the shell prompt and open up a number of shell 
windows.  Moreover, I am always editing with either vim or sometimes 
gedit and as a result, running the ruby programs from the command 
prompt.  That has to be the reason why I haven't run into these kinds of 
obscure problems yet, especially dealing with standard input/output.

I ran the program from the command prompt and it waits for my input and 
I can type on the terminal as much as I want.  However, I don't know how 
to signal the termination of the standard input.  I tried CTRL-C which 
is obviously the termination of the program.  since I see that in the 
stack trace as follows:

ex0261.rb:7:in `read': Interrupt
        from ex0261.rb:7

The seventh line of the code in the program above is:

    while data = socket.read(1)

Chris, as you suggested, I changed the buffer count to 1 instead of 512, 
but still no go.  I type the text and hit the enter key but windows just 
waits for me to enter text.  I guess it boils down to generating end of 
the input signal to windows.  In unix/linux it is CTRL-D, which does not 
work in windows.

Wolfgang, you wrote:
"the shebang will NOT work in a windows environment at all."
You mean in: $stderr.print "IO failed: " + $!
right?  Is there any other way I can write something which works in both 
Windows and Linux in a cross-platform manner?
Thanks again and regards to you all.
Bharat
