App Functions

These commands allow you to launch any HP app, bring

up any view of the current app, and change the options in

the View menu.

STARTAPP Syntax: STARTAPP("name")

Starts the app with name. This will cause the app

program’s START function to be run, if it is present. The

app’s default view will be started. Note that the START

function is always executed when the user taps in

the Application Library. This also works for user-defined

apps.

Example: STARTAPP("Function") launches the Function

app.

STARTVIEW Syntax: STARTVIEW( [,draw?])
