I'm learning Ruby from the Learn to Program tutorial by Chris Pine.
On http://pine.fm/LearnToProgram/?Chapter=01, he mentions saving a
calc.rb file after typing in "puts 1 + 2" in my text editor , then
going to the command line and typing "ruby calc.rb", and getting the
results "3" returned.
I am not getting this result; instead I'm getting a message that the
file or directory can't be found. I'm using the built-in Scintilla text
editor which comes with Ruby.
How do I get the command line to see the saved file?
Looks like you are using Scite editor. If so, you can press F5 and see
program output directly in Scite.

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.

If you are learning, you might want to try the interactive ruby interpreter: irb. That will save you writing things, saving them, and trying them. For simple tests it is very quick. To use it, go to your command line and type:
irb
And then you're be able to type "puts 1 + 2" and see the result directly.
Have fun anyway!
