;		QAR 3333
;		 AREA: CCOM3
;
;	44	FIX CODE THAT INTERCEPTS TAPE ALREADY UNLOADED ON UNLOAD

;		LEAVE THE POSSIBILITY OF A DISMOUNT MESSAGE, REQUEST, AND

;		SETTING UP INTBLK FOR THE UNLOAD TRAP.  INTBLK SHOULD BE
;		RESET TO WHAT IT LOOKED LIKE BEFORE THE UNLOAD CODE ENTERED.

;		 AREA:CKLOG3
;
;	54	DON'T GIVE "UFD RENAME ERROR 26" IF USER DISMOUNTS A F/S
;		WITH /NOWRITE SET
;		QAR 3351
;		 AREA: UFDCCB
;
;	55	DO PHYSICAL ONLY OPEN ON TTY SO IF ITS ASSIGNED AS LOGICAL
;		NAME FOR ANOTHER DEVICE, UMOUNT WILL NOT GET CONFUSED.

;		 AREA: UMSMUL
;
;	61	CHANGE PAGE PSEUDO-OPS TO FORM FEEDS
;		QAR 3330
;
;	62	EDIT 54 TRIED VERY HARD TO FIX THE RENAME ERROR, BUT
;		DIDN'T REALIZE THAT THE MONITOR HAD REGISTERED THE /RONLY
;		STATE OF THE STR. ON THE LOOKUP AND STILL TREATED IT AS
;		THOUGH IT WERE IN THAT STATE EVEN AFTER THE STRUUO TO
;		CLEAR THE /RONLY STATUS.  TO KEEP THE MONITOR ADVISED
;		OF WHAT WE'RE DOING WE MUST CLOSE THE STR (CHNL USR) 
;		BEFORE THE RENAME
;		 AREA: UFDCLF
;
;	63	EDIT 46 DID NOT ALLOW FOR CHANNEL CMU, WHICH MUST BE
;		OPENED PHYSICAL ONLY.
;		 AREA: STAR12
;
;	64	PUT IN VIDRID CONDITIONAL WHICH WILL CAUSE A VID TO BE
;		IF A REELID IS NOT SUPPLIED FOR A MAGTAPE. 
;		QAR 3307,3368
;		 AREA: MOUNT
;
;	65	ADD -1 SETTING TO RIDSW WHICH WILL NOT FORCE USER TO 
;		GIVE REELID FOR MAGTAPE MOUNT IF THE REQUEST IS GOING
;		TO THE OPERATOR. CONTINUE TO REQUIRE IT IF UMOUNT WILL
;		DO THE ENTIRE MOUNT
;		QAR 3339
;
;	66	RELEASED AS VERSION 26(66) IN APRIL, 1975
;
;	MAKE EDIT 100 THE FIRST EDIT OF 26A
;
;	100	MAKE UMOUNT SMARTER ABOUT ERSATZ DEVICES (EG. SYSA,HLPB)
;		THESE NAMES NOW GIVE VERY CONFUSING SET OF MESSAGES
;		SPR 15615
;		 AREA:MOUNT
;
;	101	REELID DOESN'T GET SET IF USER OWNS DRIVE BUT OMOUNT IS
;		NEEDED
;		SPR 16466
;		 AREA: MOOP1
;
;	102	UMOUNT DOES NOT CHECK PHYSICAL DEVICE WHEN IT SHOULD
;		IN GENERATING LOGICAL NAME
;		SPR 16467
;		 AREA: NAMPHY
;
;	103	UMOUNT GIVES 'LOGICAL NAME IN USE' MESSAGE AND GENERATES
;		NEW LOGICAL NAME WHEN IT SHOULDN'T, NAMELY IF USER
;		MOUNTS A DEVICE BY A LOGICAL NAME HE IS ALREADY USING
