Command APPDISPLAY Foundation
Displays an Application Part and activates it.
APPDISPLAY [ <oApp> ] [ MODELESS ] [ SAVE ]
The command APPDISPLAY displays an Application Part (APP) that is created by commands like APPEDIT or APPBROWSE. Those APPs which have an own dialog window are displayed in modal state by default.
Modal display means that the execution of a program is halted in the program line that issues the APPDISPLAY command. A program resumes when the APP is closed by a user.
The option MODELESS must be used to display an APP in modeless state. In this case the program is not halted but immediately continues in the line following the APPDISPLAY command. A program must include an event loop when APPs are displayed modeless (see function AppEvent()). Also, displaying multiple APPs at a time requires the MODELESS option.
