RWBROOK interface functions: System Initialization/Deinitialization.
subroutine XYZInit
Prior to everything, the RWBROOK interface must be initialized.
The best way to do that is to place the following call:
call XYZInit
somewhere on the top of your application.
NOTE 1: without initialization RWBROOK will not function.
NOTE 2: RWBROOK may be initialized only once. Repeated
initialization will cause memory fault.
