6.8.1.1 Example
Here's an example of a macro that puts a business letter template on the screen and uses recursive edits to let you type your return address, the recipient's name and address, and the date. Because the brackets on the mode line are a pretty subtle clue to what you are going to type, we'll give the user of this macro explicit instructions about what to type. Table 6-3 provides these instructions.

The following screens show what the macro defined in Table 6-3 looks like when you run it.
Type: F4
The macro pauses so that you can type your address.
Type your address and press: C-M-c
The macro pauses so you can type the recipient's name and address.
Type the recipient's name and address and press: C-M-c
The macro pauses so you can type the date.
Type the date and press: C-M-c
The macro finishes by typing the opening for the letter.
Now the macro has finished editing; you can type the recipient's name and then the body of the letter, and of course you can go back and edit any of the information you've already filled in.
