Program:
« LST TMENU »
`OWGT ‰
Use WGT to calculate the mass of an object of weight 12.5 N. The program sets up the menu, then completes
execution.
J%WGT%
Select the SI unit system, which starts the program in the menu list.
%SI%
Key in the weight, then resume the program.
12.5 !æ
Example:
The following program, EIZ, constructs a custom menu to emulate the HP Solve application for a
capacitive electrical circuit. The program uses the equation E = IZ, where E is the voltage, I is the current, and Z
is the impedance.
Because the voltage, current, and impedance are complex numbers, you can't use the HP Solve application to
find solutions. The custom menu in EIZ assigns a direct solution to the left-shifted menu key for each variable,
and assigns store and recall functions to the unshifted and right-shifted keys — the actions are analogous to the
HP Solve application. The custom menu is automatically stored in CST, replacing the previous custom menu —
you can press !£ to restore the menu.

Comments:
Displays the custom menu
stored in LST.
Stores the program in WGT.
Comments:
Sets Degrees mode. Sets flags
–15 and –16 to display complex numbers in
polar form. Sets the display mode to 2 Fix.
Starts the custom menu list.
Builds menu key 1 for E.
Unshifted action: stores the object in E. Left-shift
action: calculates I × Z, stores it in E, and
displays it with a label. Right-shift action: recalls
the object in E.
Builds menu key 2.
