Module usx - Userexit Call

The module usx (userexit interface) provides the interface to the DataView userexit module.

Userexits are called at the triggers of the DataView dialog objects. However, you can also use the userexit interface for your own applications if the name of the calling function depends on variables only known at runtime or if you do not want to assign fixed pointers for the calling structure.
