Creating menus

The HP 49G enables you to create a custom menu. The menu can contain

labels for operations, commands, and other objects that you create or

group together for your convenience.

A custom menu is identified by the reserved variable GST. Therefore, you

create a custom menu by naming a list of menu items GST. You can also

use the

MENU

command to store a list in GST.

A custom menu is a type of function key menu; that is, the items on the

menu appear across the bottom of your screen and can be selected by
pressing the corresponding function key.

You can create a custom menu—that is, a GST variable—in each directory.
This enables you to have a different custom menu in each directory.

To create a custom menu

1. Enter a list of label-object pairs, one pair for each menu item.

The syntax for each label-object pair is {“label”, object j. Also, to
prevent an object being evaluated, you should enclose the object in

tick marks ("). Each pair is a sub-list within the main list.

Objects can be of many types, such as variable names, programs,
strings, and imit objects. For example:

H"m^3", 'Ijn^s'l, {"VOL", VOLUME), {"TIME", 'TIME()'l!

In this example, the menu items will be labelled m*3, VOL, and TIME
respectively. The first inserts the cubic metre imit expression, the

second inserts the string “VOLUME”, and the third returns the current

time.

2. Press ® to move the cursor outside the main list.

3. Press (ST®.

4. Enter GST.

5. Press®

In RPN mode: follow steps 1, 4, and 3.
