You need to set your path top the Ruby bin directory.  The error: 'ruby' is
not recognized as an internal or external command,
operable program or batch file.'

Is do to this you must set PATH=%PATH%;c:\ruby\bin or the true path of your
installation.


The reason your calc.rb at the command line is working is

Depending on how you installed windows...1click installs set this up.

On Windows it depends whether or not .rb files are associated with ruby. It
seems perhaps they are.  Since you type calc and cal.rb and it works I
believe this to be the best guess.

So as I understand it you are are experiencing.

$ hello-world.rb
Hello world

No I would check the the following:

$ assoc 

Look for 
.rb=RubyScript

$ ftype  

Look for
RubyScript="c:\ruby\bin\ruby.exe" "%1" %*


For more assistance on these commands run "help assoc" and "help ftype".

If this does not have either entry.


See if that helps
