You may be opening the command prompt in some default home directory, 
which is not the same place where you saved the Ruby file.

When you save the file in Scintilla, make sure you save it to c:\calc.rb

Then, when you get a command prompt, go to the C: drive, then change to 
the root drive:

   c:\>  cd \

Then try running ruby calc.rb.


If that works, all is good.

You will probably be able to run it by just typing the file name and 
hitting Enter, too, if the Ruby installation set up the filetype 
execution association for you.

Now, I don't generally advocate saving your files to the root of the C: 
drive, so decide where you want to place the files, and then just figure 
out how to navigate there once you have a command prompt.
