This a brief step-by-step guide to editing programs.
1.	Start Emacs by use of the emacs button in the button-bar. An empty Emacs window called
	*scratch* appears. Move the cursor to the Emacs window and click the left mouse				button
	to select this window. Do not type your program in the *scratch*			window.
2.	To create an SML program buffer for a program called “ gcd.sml”, type Ctrl-xCtrl-f,
	then gcd.sml, then press return. (Alternatively, use the Files menu.)
	If the file	gcd.sml exists on disk already, it is loaded into Emacs. Otherwise a new empty
	buffer is created. The suffix “ .sml” is important: it puts the buffer in Sml mode.
3.	Type and edit your program in the SML program buffer. Editing commands are described in the
	reference card.
4.	Type Ctrl-xCtrl-sto save the program in a file on the disk. (Alternatively, use the Files
	menu.)
5.	To load the program into an SML session, type Ctrl-cCtrl-bin the SML program buffer.
