Entering a Command Line
You can enter on a command line any instruction or expression that you could execute on 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.
To move the cursor down to the next new command line, press b. You cannot move to
the next new command line by pressing #. However, you can return to existing command
lines to edit them by pressing $.
Menus and Screens in the Program Editor
TI
-86 menus and screens may be altered when displayed in the program editor. Menu items
that are invalid for a program are omitted from menus. Menus that are not valid in a
program, such as the 
LINK
 menu or 
MEM
 menu, are not displayed at all.
When you select a setting from a screen such as the mode screen or graph format screen,
the setting you select is pasted to the cursor location on the command line.
A command line that is longer
than the screen is wide
automatically continues at the
beginning of the next line.
All 
CATALOG
 items are valid
in the program editor.
