I've done a lot of utility programs for Windows that don't need or want a GUI. A few lines of text input and they churn away. On Windows, you do this by invoking the "console", the successor to the MS-DOS screen. Then the Windows API provides routines for clearing the screen, positioning the text cursor, choosing a text color, etc. I can do this with several programming languages; they aren't a problem as long as I have a syntax manual. Problem is, my wife bought a Mac. I'd like to convert a lot of these to the Mac, but I need a way to access a non-user-interface screen and access to commands like those I mentioned via a programming language. Can someone help me?
