Control Signals
These bits [128-255] used by the DLL for communication with the VB and AcroBasic.
The MotionCore.DLL depends on these bits so don’t use them in your Vb programs for any other purpose than
as defined below. If you need to use some bits for your program logic, we have set aside some User Scratch Pad
bits at bit locations (224-248) that you may use as desired.
