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.
