Sometimes it would be convenient to have some values that are available to all opened screens, i.e. values with
global scope with respect to the current realtime application - Hence "global" variables.
In RealTime, there is an array of 20 "system global variables", indexed 1 to 20. A data value can be linked to one of
these global variables by setting either the "Get from Global index" (sources the value from the global variable) or the
"Put in Global Index" (writes the value to the global variable). This allows sharing of some data between screens.
