I. The Command Menu-Path Table

This lists the calculator’s programmable commands in CAT order. Of the 818 commands, 808 are shown by CAT. This list assumes that library 256 is attached, flag –95 is off, and flag –117 is set.

“Keys” column:

Each command identifies its menu path or key sequence (if any) with alternatives on additional lines. “/” means “either”. The most efficient key sequence is shown first if several exist, assuming that NXT NXT is better than PREV, etc. “[]” = optional.

!key ALPHA-RS-2; MTH NXT PROB

This means that you can either press [ALPHA] [RIGHT-SHIFT] [2] or press [MTH] [NXT] [PROB] [!] to get the ! function.

+key 95.1

This means that [+] is on the keyboard in row 9, column 5. The

.1 means unshifted;

.2 means left-shifted;

.3 means right-shifted;

.4 means alpha-shifted;

.5 means alpha-left-shifted; and

.6 means alpha-right-shifted.

.01 added means hold down the shift key while pressing the key, e.g. key 22.21 is MODE with the left-shift key held down, also called LS&MODE.

AMORT

79 MENU

This means that AMORT is not in any keyboard menu, but you can find it in numbered menu 79 (type 79 MENU to go to that menu).

QUOT

«POLYNOMIAL» NXT; ARITH POLY PREV

This means that QUOT is in the POLYNOMIAL menu, a special menu which is neither a numbered menu, nor on the keyboard, but is seen by executing the «programmable» command POLYNOMIAL. QUOT can also be found in the ARITH POLY PREV menu.

Other columns:

Type: “F” is function, “C” is command, and “A” is analytic function.

Library: The internal library number and command number identifying the command. If there are multiple, they are listed one per line.

Size: Amount of memory taken in a program by this command, in bytes

Menu: The menu ID containing this command, accessible with the MENU command. If there are multiple, they are listed one per line.

?: An “H” means this command has a HELP screen. An “-” means “not shown in the CATalog”.

First: For identifying backwards compatibility, this is the first calculator model (28C, 28S, 48SX, 48GX) or ROM version (49G through the 50g) with the command.
