Appendix A:
Functions and Instructions
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 either keystrokes that are valid in the program editor only or ones that paste certain
instructions when you are in the program editor. 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.
