7.4.5.3 Response to a custom widget signal
Description
In Run MyScreens it is possible to respond to a particular signal (invokeSub()) of the custom
widget and call up a subprogram (SUB).
10 global variables, the so-called SIGARG, are available for passing values (custom widget
signal -> SUB), which are comparable to registers (REG) in configuration. This is where the
values transferred with the custom widget signal are stored.
