Scope	Name	Type	Initial	Comment
Constant	gcdwCOBIDMask	DWORD	16#1FFFFFFF	Bit Mask for calculating the CANID. Example: dwCOBID := pMsg^.cobId AND MASKS.gcdwCOBIDMask
	gcdwTXMask	DWORD	16#80000000	Bit Mask for calculating the Tx bit. Example: xTxMsg := (pMsg^.cobId AND MASKS.gcdwTXMask) > 0
	gcdwRTRMask	DWORD	16#40000000	Bit Mask for calculating the RTR bit. Example: xRTRMsg := (pMsg^.cobId AND MASKS.gcdwRTRMask) > 0
	gcdwEIDMask	DWORD	16#20000000	Bit Mask for calculating the EID (= Extended Identifer; 29 bit) bit. Example: xEIDMsg := (pMsg^.cobId AND MASKS.gcdwEIDMask) > 0
	gcbyDLCMask	BYTE	16#F	Bit Mask for calculating the message length. Example: dwLength := pMsg^.byLen AND MASKS.gcbyDLCMask
	gcbyPrioMask	BYTE	16#70	Bit Mask for calculating the message priority. Example: dwPrio := pMsg^.byLen AND MASKS.gcbyPrioMask
	gcbySyncMask	BYTE	16#80	Bit Mask for calculating the Sync bit. Example: xSync := (pMsg^.byLen AND MASKS.gcbySyncMask) > 0
