Userexits at the Start and the End of a Program

For program functions in the start procedure of the program a userexit with the userexit name INIT, which enables the datadriven initialization of user functions, is available. So frequently used masks can be already opened when starting the system. The standard name for the userexit INIT can be overwritten user specific via the default variable USXINIT in the DataView default data list.

By defining and installing a userexit named EXIT you can realize program functions these are called when leaving DataView. This method can be used to reset application-specific initializations you included into the main program main.c to their previous values.
