Functions return a value, list, or matrix. You can use functions in an expression.

Instructions initiate an action. Some functions and instructions have arguments.

Optional arguments and accompanying commas are enclosed in brackets ( [ ] ).

For details about an item, including argument descriptions and restrictions, turn

to the page listed on the right side of the table.

From the CATALOG, you can paste any function or instruction to the home

screen or to a command line in the program editor. However, some functions

and instructions are not valid on the home screen. The items in this table

appear in the same order as they appear in the CATALOG.

† indicates keystrokes that are valid in the program editor only. Some keystrokes

display menus that are available only in the program editor. Others paste mode,

format, or table-set instructions only when you are in the program editor.
