Making a folder for these programs on Windows

First, you need to get into a "command window", like this:

Click Start, then Run (which might be under "Applications"), and in the box tell it to run "cmd". This starts up a command window. In a command window, you are always in some particular folder (the "current folder"), and the "prompt" at the lower left corner of the window tells you the name of that folder. Make a folder under the current folder that you are in, to contain these files (suggested name "astro"): type

	mkdir astro
and hit the "Enter" ("Return") key. You always have to hit Enter after typing this or any other command, to make the computer do it.

Move into the astro folder: type

	cd astro
and hit "Enter". Take note of the folder you are now in, as shown by the "prompt" at the lower left corner of the window. You will need to know it later, when you unzip files.

Running these programs on Windows

First, you need to get into a "command window", like you did when setting this up:

Click Start, then Run, and in the box tell it to run "cmd". This starts up a command window. In a command window, you are always in some particular folder, and the "prompt" at the lower left tells you which one. You stored and unzipped the programs into the "astro" folder, which is under the current folder, so type the following to move into that folder:

	cd astro
and hit the "Enter" ("Return") key. You always have to hit Enter after typing this or any other command, to make the computer do it.

At this point you are ready to run any of the programs you have downloaded. At the link for each program there is a description of how to use the program. In each case you will type a command line and hit "Enter". If you want to change something and run it again, you can use the "up" arrow to bring back the previous command. Then use the left and right arrows to move back and forth, and backspace or delete to remove characters, and type new characters that you want, hitting the "insert" key if you want to insert them without overwriting later characters. Then hit Enter to run it.
