You can enter on a command line any instruction or expression
that you could execute from the home screen. In the program
editor, each new command line begins with a colon. To enter more
than one instruction or expression on a single command line,
separate each with a colon.
Note: A command line can be longer than the screen is wide;
long command lines wrap to the next screen line.
While in the program editor, you can display and select from
menus. You can return to the program editor from a menu in
either of two ways.
• Select a menu item, which pastes the item to the current
command line.
• Press ‘.
When you complete a command line, press Í. The cursor
moves to the next command line.
Programs can access variables, lists, matrices, and strings saved
in memory. If a program stores a new value to a variable, list,
matrix, or string, the program changes the value in memory
during execution.
You can call another program as a subroutine (page 16.15 and
page 16.22).

executing, the busy indicator is on.
