6.2.3 Using the Editor
The editor of the computer is used for creating and editing programs, as we saw with
our HELLO program. This section takes you further along the path of using the editor
effectively to create and edit useful C programs.
Entering the editor
You can enter the editor either from the MENU mode (by pressing 3 for the C
mode, and the S for the editor), or from the interpreter (by entering the EDIT
command).
