EFN -- THE EVENTFLAG UTILITY
		============================
 EFN can inspect and SET/CLR global or group global event flags
 EFN can inspect local event flags for a specified task
 Using EFN:  (FLG is decimal flag number)
 Global flags  ( 32 < FLG < 65 )
 	EFN>G			Inspect all global flags
 	EFN>FLG			Inspect flag number FLG
 	EFN>FLG(S/C)		Set/Clear flag number FLG

 Group global flags ( 64 < FLG < 97 ) (GRP is octal group number)
 	EFN>GR			Inspect all group global flags
 	EFN>GR/GR=GRP		Inspect all group global flags for group GRP 
 	EFN>FLG			Inspect flag number FLG
 	EFN>FLG/GR=GRP		Inspect flag number FLG for group GRP 
 	EFN>FLG(S/C)		Set/Clear flag number FLG
 	EFN>FLG(S/C)/GR=GRP	Set/Clear flag number FLG for group GRP
 	> Note after specifying GRP once it remains default
  
 Local flags  ( 0 < FLG < 33 )
 	EFN>L/t=TSK		Inspect all local flag for task TSK
 	EFN>FLG/t=TSK		Inspect local flag number FLG for task TSK
 	EFN>FLG(S/C)/t=TSK	Set/clear local flag number FLG for task TSK
