15-10 Programming
Aplet naming convention
To assist users in keeping track of aplets and associated
programs, use the following naming convention when setting
up an aplet’s programs:
• Start all program names with an abbreviation of the aplet
name. We will use APL in this example.
• Name programs called by menu entries in the VIEWS
menu number, after the entry, for example:
– APL.ME1 for the program called by menu option 1
– APL.ME2 for the program called by menu option 2
• Name the program that configures the new VIEWS menu
option APL.SV where SV stands for SETVIEWS.
For example, a customized aplet called “Differentiation”
might call programs called DIFF.ME1, DIFF.ME2, and
DIFF.SV.
Customizing an aplet example
This example aplet is designed to demonstrate the process of
configuring an aplet. The new aplet is based on the Function
aplet. Note: This aplet is not intended to serve a serious use,
merely to illustrate the process.
Save the aplet
1. Open the Function aplet and save it as “EXPERIMENT”.
The new aplet appears in the Aplet library.
>$3/(7@ Select
Function T6W@—
>$/3+$@ EXPERIMENT
PF—
2. Create a program called
EXP.ME1 with contents
as shown. This program
configures the plot
ranges, then runs a
program that allows you
to configure the angle format.
