- Static process handle is unique to each application. It follows slot number and application order in slot (1-31 for internal slot, 32-63 for slot 1, 64-95 for slot 2, 96-127 for slot 3, 128-255 for installed applications). Index handle is always 1, Pipedream handle is 3...
- Dynamic process handle (PID equivalent) is unique to each suspended or running process (range 2-127, Index PID is always number 1).
