Thank you for your help. I tried to follow these directions, but it didn't work. I'm not sure I understand them correctly. Steps 1 and 2 are fine, but maybe I didn't do step 3 or 4 the right way. Here's what happened:
I have a folder with MzScheme in it and a folder with arc3 in it. I entered "cd" and the directory of the arc3 folder: "cd C:\Program Files\Arc\arc3" and then I hit enter. The next line looked like this:
C:\Program Files\Arc\arc3>
so I typed in "mzscheme -m -f as.scm" and pressed enter.
This message appeared: 'mzscheme' is not recognized as an internal or external command, operable program, or batch file.
Do I need to be more specific with my directory path? Is there a file inside the arc3 folder that I need to name? Or am I not executing "mzscheme -m -f as.scm" when I type it in?
Ok, so the problem is that windows doesn't know where to find mzscheme.
To rectify the situation, you could either type in the full path to mzscheme instead of just it's name, or you could add it to your PATH variable (that's where windows looks to locate programs when you type them in on the command line)
Here's how to do that temporarily:
PATH=%PATH%;<insert mzscheme path here>
Again, that's PATH=%PATH%, followed by a semicolon and then the path to mzscheme. Unfortunately, this is a temporary fix that will only last as long as that command window.
To make it permanent: right click on "Computer" and go to properties. Somewhere there should be an Advanced Settings link, which should pop up a new window. Click the Environment Variables button, and edit the PATH variable (either for your user or the whole system). Add a semicolon, and then paste in the path to the mzscheme executable.
