Entering a Program Command Line
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.
