;VERSION 5A COMMENT
;
;	THIS EDIT APPLIES TO BOTH DBMS-10/20. THE CORRESPONDING
;	EDIT NUMBER FOR DBMS V5 IS 455.
;
;SYMPTOM:
;
;	WHEN A MEMBER RECORD IN A SET OCCURRENCE HAS BINARY ZEROES IN 
;	ITS SET POINTERS, FIND NEXT AND FIND PRIOR GET INTO AN INFINITE 
;	LOOP.
;
;DIAGNOSIS:
;
;	FIND RSE 3 IS NOT EXPECTING CORRUPT DBKEYS IN THE SET POINTERS,
;	SO WHEN IT SEES ZEROES IN THE PARTICULAR SET POINTERS, IT THINKS
;	THAT SOME OTHER CONCURRENT RUN-UNIT IS WORKING WITH THIS RECORD.
;	IN ORDER TO GUARD AGAINST THIS POSSIBILITY, IT DEFINES A
;	CANONICAL NEXT OF SET, WHICH IS TYPICALLY THE RECORD WHICH IT IS
;	CURRENTLY WORKING WITH. THUS, IN THE CORRUPT SITUATION, IT
;	RE-FINDS THAT RECORD AND LOOPS INFINITELY. WHEN DBCS HAS FOUND
;	A RECORD, IT DOES NOT SPOT-CHECK THE SET POINTERS WHICH IT
;	CONTAINS FOR BINARY ZEROES. 
;
;	HOWEVER, IF CORRUPT SET POINTERS ARE NON-ZERO, THIS FACT WILL
;	BE CAUGHT UNDER THE XX22 ERROR-STATUS CODE BECAUSE THIS TYPE
;	OF CURRUPT SET POINTER WILL POINT OFF TO AN AREA OR DATA BASE
;	PAGE OR RECORD WHICH IS INCONSISTENT WITH THE WITHIN DEFINITION
;	FOR THE RECORD TYPE IN THE SCHEMA, OR WILL POINT OFF TO SOME
;	DATA BASE PAGE WHICH IS NOT DEFINED FOR AN AREA.
;
;	ALSO, IF AN OWNER RECORD CONTAINS BINARY ZEROES IN ITS SET
;	POINTERS THIS IS ALSO ALREADY REPORTED UNDER ERROR-STATUS XX22.
;
;CURE:
;
;	INSTALL EDIT 521 FOR DBMS-10/20 V5A, WHICH WILL SPOT-CHECK
;	SET POINTERS FOR THE PARTICULAR SET IN THE RECORD FOR BINARY
;	ZEROES. IF IT FINDS SUCH, IT WILL ISSUE AN ERROR-STATUS CODE
;	OF 0356.
;

;VERSION 5A COMMENT
;
;	THIS EDIT, WHICH WAS EDITS 411/451 FOR DBMS-10/20 VERSION 5 
;	DID NOT MAKE IT INTO VERSION 5A. ALSO, PLEASE NOTE THAT THE
;	LIBRARY FILE DBSANY.REL IS BEING CHANGED TO DBSINF.REL IN
;	THE MAKLIB STEP BELOW, IN ACCORDANCE WITH EDITS 522/523. 
;	THE SYMPTOM, DIAGNOSIS AND CURE FOR EDITS 411/451 ARE BEING 
;	REPRODUCED HERE FOR YOUR CONVENIENCE.
;
;SYMPTOM
;
;	(411)
;	USING SCHEMAS CONTAINING DDL USING INTERSPERSED "AREA NAME",
;	"RECORD NAME" AND "SET NAME" SYNTAX, DBINFO MAY FAIL WITH
;	THE MESSAGE "?INFSAF -- SCHEMA ACCESS FAILURE".
;
;	(451)
;	WITH EDITS 411 AND 412 INSTALLED, THE DBINFO FUNCTIONS 
;	/DISPLAY DATA:"SET-NAME" AND /DISPLAY USAGE:"SET-NAME" MAY
;	REPORT NO DATA WHEN APPROPRIATE DATA EXISTS ON THE DBMS
;	DATA BASE.
;
;
;DIAGNOSIS
;
;	(411)
;	DBINFO DOES NOT BIND SUCH SCHEMAS PROPERLY BECAUSE THE
;	INTERNAL NAME-ID'S FOR THE USER-DEFINED SYMBOLS IN THE 
;	SCHEMA GET OUT OF SEQUENCE WITH THE TID'S ASSIGNED FOR
;	USER'S RECORD TYPES. THIS IS REALLY A SCHEMA PROBLEM, AS
;	THE SCHEMA PROCESSOR MAY INADVERTENTLY OVERLAP AN IN-CORE
;	WORK AREA FOR PROCESSING RECORD TYPES AND SET TYPES. HOW-
;	EVER, COBOL PROGRAMS USING SUCH SCHEMAS BIND AND EXECUTE
;	PROPERLY. COBOL DOES THE BIND IN TWO STAGES. FIRST, AT
;	COMPILE TIME IT FOLLOWS THE LINKED LIST OF RECORD-TYPES
;	IN THE .SCH FILE WHEN IT IS CREATING THE BIND STATEMENTS.
;	AS A RESULT, THE NAME-ID'S FOR THE VARIOUS DATA-NAMES ARE
;	IN ASCENDING ORDER ALTHOUGH THE BIND STATEMENTS MAY NOT
;	BE IN ORDER AS DEFINED IN THE SCHEMA. AT RUN-TIME DBCS
;	EXPECTS THE NAME-ID'S TO BE IN ORDER, AND USES THE TID'S
;	TO CREATE A TABLE OF REFERENCES TO THE RECORD TYPES IN
;	THE IN-CORE DATA BASE. ON THE OTHER HAND, DBINFO TRIES THE
;	SAME THING IN ONE PASS, BUT IT IS NOT SMART ENOUGH TO
;	SHUFFLE THE RECORD TYPES IN THE SAME WAY. AS A RESULT,
;	THE NAME-ID'S GET OUT OF SEQUENCE AS DBINFO ATTEMPTS TO
;	BIND THE RECORD TYPES IN SUCCESSION.
;
;	IT WAS DECIDED NOT TO FIX THE PROBLEM IN SCHEMA BECAUSE
;	OF THE FACT THAT IT CAUSES NO PROBLEMS FOR COBOL (OR FOR
;	FORTRAN). AS A RESULT, DBINFO IS BEING MODIFIED IN 
;	ORDER TO CONTAIN THE PROBLEM AT THE POINT WHERE AN EDIT
;	WILL HAVE THE FEWEST POTENTIAL REPERCUSSIONS.
;
;	(451)
;	AFTER EDIT 411 IS THROUGH SHUFFLING THE RECORD LIST FOR THE
;	SUB-SCHEMA BINDING PROCESS IN DBINFO, IT FAILS TO CLEAR THE
;	LEFT HALF OF THE WORD FOR THE AFFECTED MEMBERS OF THIS LIST.
;	THESE TWO DBINFO FUNCTIONS USE THE ENTRIES OF THIS LIST IN
;	ORDER TO SEE IF THE CURRENT DATA BASE RECORD IS AN OWNER OF
;	THE SPECIFIED SET TYPE. IF THE LEFT HALF OF THE ENTRY IN
;	THE RECORD LIST IS NOT CLEARED, THE COMPARISON WILL FAIL 
;	WHEN IT SHOULD PASS.
;
;CURE
;
;	INSTALL EDIT 524, CAUSING DBINFO TO RETAIN INFORMATION
;	IN ITS IN-CORE TABLE OF REFERENCES AS TO WHAT ORDER THE
;	RECORD TYPES SHOULD HAVE BEEN IN. THE ORIGINAL ENTRIES
;	ARE A SERIES OF HALF-WORD ADDRESSES IN THE RIGHT HALF OF
;	EACH WORD, AND THE LEFT HALF OF EACH REMAINS AT 0 FOR
;	THE ENTIRE RUN OF DBINFO. IT IS THE LEFT HALF OF THESE
;	WORDS WHICH ARE BEING USED FOR THE PURPOSES OF THIS EDIT.
;
;	(451)
;	ALSO, WHEN THE WORK OF EDIT 411 IS COMPLETE, CLEAR THOSE
;	LEFT HALF-WORDS.
;
;
;WARNINGS
;
;	WHEN THIS EDIT IS INSTALLED INTO DBINFO, ITS "DISPLAY
;	DATA" FUNCTION STILL WILL NOT KNOW WHERE TO LOOK IN THE
;	IN-CORE DATA BASE FOR THE INFORMATION ON RECORD TYPES
;	WHICH ARE OUT OF ORDER, AND IT WILL PRODUCE THE MESSAGE
;	"?INFDAF -- DATA BASE ACCESS FAILURE". IN ORDER TO CLEAR
;	THIS PROBLEM, YOU MUST INSTALL EDIT 525.
;
;	EDITS 524 AND 525 ARE INTENDED TO FIX A VERY SPECIALIZED
;	PROBLEM AS EXPLAINED ABOVE, AND YOU NEED NOT INSTALL THEM
;	UNLESS YOU CONSTRUCT YOUR SCHEMA DDL IN THE UNUSUAL FASH-
;	ION AS INDICATED UNDER "SYMPTOM" ABOVE AND YOU ARE EXPER-
;	IENCING THIS PROBLEM.
;
;	ALSO, WHEN THE "DISPLAY MAP" FUNCTION IS USED, DBINFO WILL
;	PUT THE LISTINGS FOR THE RECORD TYPES WHICH ARE OUT OF
;	ORDER AT THE BOTTOM OF THE "MAP" REPORT. THE CONTENTS OF
;	THESE LISTINGS WILL BE ACCURATE. IT WAS DECIDED NOT TO
;	FIX THIS PROBLEM AT THIS TIME, AS IT WOULD HAVE REQUIRED
;	A MAJOR RE-WRITE OF THE "MAP" FUNCTION IN ORDER TO OVER-
;	COME WHAT AMOUNTS TO A MINOR INCONVENIENCE FOR THE USER.
;
;	FINALLY, DO NOT INSTALL THIS EDIT UNTIL AFTER YOU HAVE INSTALLED
;	EDIT 522 FOR DBMS-20 OR EDIT 523 FOR DBMS-10.
;
;NOTE ***** THIS EDIT APPLIES TO DBINFO FOR DBMS10 + DBMS20 VERSION 5A
;		BUT NOT TO COBOL AND FORTRAN
;
;THE RECOMMENDED FILENAME FOR THIS EDIT IS 524.FIX.    THE LINES
;.EDIT THRU .ENDE SHOULD BE TYPED INTO THAT FILE
;
;
;	FOR DBINFO APPLY THIS EDIT TO DBSINF.REL **********
;
;	NOTE: THE MAKLIB STEP BELOW OUTPUTS DBSINF.REL FROM YOUR INPUT
;	DBSANY.REL. THE INPUT DBSANY.REL WILL BE UNCHANGED AND REMAINS
;	SUITABLE FOR FUTURE EDITS TO DBSANY.REL FOR DBCS FOR LIBOL AND 
;	FORLIB.
;
;
;THE EDIT CAN BE INSERTED USING THE FOLLOWING COMMANDS:
;
;FOR DBMS-10

;VERSION 5A COMMENT
;
;	THIS WAS EDIT 430 IN VERSION 5. CHANGES TO THE MAKLIB TEXT
;	FOR VERSION 5A ARE FLAGGED WITH [V5A] IN THE MARGINAL COMMENTS.
;	ALL CHANGES REPRESENT CHANGES OF ADDRESS FOR EXPANDED IN-LINE
;	LITERALS.
;
;	NOTE: VERSION 5 EDITS 430 AND HIGHER WERE CREATED AFTER THE 
;	CUTOFF DATE FOR VERSION 5A. CONSEQUENTLY, THERE WAS NO OPPORTUN-
;	ITY TO INTEGRATE THEM INTO THE RELEASED VERSION OF V5A.
;	ALL SUCH EDITS FOR VERSION 5A WHICH HAVE A CORRESPONDING
;	VERSION 5 EDIT WILL BE DOCUMENTED WITH A VERSION 5A COMMENT
;	PREFIX SUCH AS THIS ONE.
;
;SYMPTOM
;
;	IF ORDER IS SORTED DUPLICATES ARE FIRST/LAST/UNSPECIFIED
;	ALLOWED IS SPECIFIED IN THE ORDER CLAUSE OF A SET TYPE
;	WHICH HAS MEMBERSHIP CONSISTING OF MULTIPLE MEMBER REC-
;	ORD TYPES, ENTER MACRO FINS6 WILL NOT NECESSARILY RE-
;	TRIEVE THE PROPER MEMBER RECORD TYPE WHEN A MATCH IS
;	FOUND ON THE USER-SUPPLIED SORT KEY VALUE.
;
;DIAGNOSIS
;
;	FOR A SET OCCURRENCE WITH ORDER SORTED DUPLICATES ...
;	AS SPECIFIED ABOVE, FINS6 FAILS TO CHECK THE RECORD
;	TYPE OF THE MEMBER RECORD WHEN A USER KEY MATCH IS
;	FOUND BECAUSE THE INTERNAL RECORD TYPE ID IS NOT PART
;	OF THE SORT KEY FOR THE SET TYPE. THIS PROBLEM APPLIES
;	FOR RANGE KEY MATCHES AS WELL AS FOR EXACT KEY VALUE
;	MATCHES. FINS6 WORKS APPROPRIATELY FOR ALL OTHER TYPES
;	ORDER SORTED WITH EITHER EXACT OR RANGE KEY MATCHES.
;
;CURE
;
;	SINCE FINS6 REQUIRES THE USER TO SUPPLY A RECORD NAME
;	AS A "USING" PARAMETER AS WELL AS A SET NAME, IT AP-
;	PEARS ONLY PROPER THAT IT SHOULD CHECK FOR RECORD TYPE
;	AS WELL AS USER KEY VALUE. INSTALL EDIT NO. 540 IN
;	ORDER TO MAKE IT DO THIS EXTRA CHECKING FOR ORDER
;	SORTED DUPLICATES.
;
;	THIS LARGE AND COMPLEX PATCH AFFECTS RETRIEVAL THRU 
;	FINS6 ON THE FOURTH OF THE FOUR MAJOR TYPES OF SORTED 
;	SETS, WHICH MAY NOT NECESSARILY BE USED AT ALL SITES. IT
;	IS COMPLEX BECAUSE CHECKING MUST BE DONE FOR RANGE KEY
;	MATCHES AS WELL AS FOR EXACT KEY MATCHES. FOR RANGE KEY
;	MATCHES, WE HAVE TAKEN THE INTERPRETATION THAT A RANGE
;	MATCH EXISTS ONLY IF TWO CONDITIONS EXIST. THE FIRST IS
;	AS SPECIFIED IN THE DBMS VER 5 ADMINISTRATOR'S MANUALS
;	FOR RANGE KEY MATCHES ON PAGE 4-21 TECHNICAL NOTES 8 AND
;	9 AND ON PAGE 4-23 TECHNICAL NOTE 9. HOWEVER, THE LIST
;	OF CONDITIONS GIVEN IN NOTE 9 ON PAGE 4-23 APPLIES TO 
;	BOTH MODES OF SET OCCURRENCE SELECTION -- CURRENT OF SET
;	AS WELL AS LOCATION MODE OF OWNER. THE OTHER FORMS OF 
;	ORDER SORTED WHERE DUPLICATES ARE ALLOWED CURRENTLY 
;	ADHERE TO THIS INTERPRETATION. THE SECOND IS THAT
;	THE INTERNAL TYPE ID OF THE FOUND RECORD MUST MATCH THE
;	RECORD TYPE SPECIFIED BY THE USER AS THE "RECORD NAME"
;	PARAMETER SUPPLIED TO FINS6 UNDER ORDER SORTED DUPLICATES.

;VERSION 5A COMMENT.
;
;	THIS WAS EDIT 456 FOR VERSION 5. NO CHANGES WERE REQUIRED
;	IN THE MAKLIB TEXT.
;
;SYMPTOM:
;
;	WHEN THE CALC CHAIN POINTER IN A CALC RECORD POINTS TO ITSELF,
;	WITH DUPLICATES NOT ALLOWED THE USER PROGRAM HANGS, BUT WITH
;	WITH DUPLICATES ALLOWED THE USER PROGRAM LOOPS.
;
;DIAGNOSIS:
;
;	FIND RSE 5 IS NOT EXPECTING A CALC-CHAIN POINTER TO POINT TO
;	ITSELF, AND IT ACCEPTS THIS CORRUPT POINTER AS THE POINTER
;	TO THE NEXT RECORD ON THE CALC CHAIN. THIS KIND OF CORRUPTION
;	CAN OCCUR IF AN ERROR-STATUS CODE IS ISSUED ON A STORE OF A
;	CALC RECORD AND THE FAILED STORE IS NOT PROPERLY BACKED OUT.
;	FIND RSE 5 CHECKS FOR OTHER KINDS OF INCONSISTENCIES ON CALC-
;	CHAIN POINTERS, HOWEVER.
;
;CURE:
;
;	INSTALL EDIT 551 FOR DBMS-10/20 V5A, WHICH WILL SPOT-CHECK
;	CALC-CHAIN POINTERS TO SEE IF THEY POINT BACK TO THEMSELVES.
;	IF IT FINDS THIS CONDITION, IT WILL ISSUE AN ERROR-STATUS CODE
;	OF 356.

;VERSION 5A COMMENT

;	THE CORRESPONDING EDIT FOR VERSION 5 IS EDIT 467.
;
;SYMPTOM:
;
;	A DML PROGRAM USING ENTER MACRO JRDATA, WHICH OMITS THE SECOND
;	PARAMETER INDICATING THE NUMBER OF WORDS OF NON-PRINTING DATA

;
;DIAGNOSIS:
;
;	JRDATA NEVER CHECKS TO SEE IF THIS REQUIRED PARAMETER IS PRESENT
;	AND MERELY ASSUMES THAT IT IS THERE.
;
;CURE:
;

;SYMPTOM:
;
;	WHEN USING DBMEND TO DO THE FIRST OPEN ON A SYSTEM AREA WHICH
;	JUST BEEN CREATED BY THE SCHEMA PROCESSOR, DBMEND DOES NOT
;	CREATE THE SYSTEM RECORD AND INITIALIZE THE SETS WHICH IT OWNS.
;
;DIAGNOSIS:
;
;	DBMEND IN VERSION 5A DOES NOT KNOW ABOUT RECORDS AND SETS, EXCEPT
;	FOR THE AREA STATUS RECORD, AS IT ONLY KNOWS ABOUT DATA BASE
;	AREAS AND PAGES. SO, WHEN IT OPENS A NEWLY CREATED AREA, IT DOES
;	NOT KNOW THAT IT IS BEING EXPECTED TO CREATE THE SYSTEM RECORD
;	WHEN IT OPENS THE SYSTEM AREA. IT WOULD BE EXTREMELY DIFFICULT
;	TO TEACH DBMEND ABOUT THE SYSTEM RECORD, AND BESIDES DBMEND
;	SHOULD NOT BE USED TO OPEN OR FORCEOPEN A NEWLY CREATED AREA.
;	RATHER, A USER-PROGRAMMED RUN-UNIT SHOULD BE DOING THIS INSTEAD.
;	SO, THE BEST APPROACH IS FOR DBMEND TO GIVE AN ERROR MESSAGE IF
;	IT IS USED IN THIS CIRCUMSTANCE. SINCE DBMEND DOES NOT KNOW ABOUT
;	RECORDS, WE CAN USE THIS FACT AS A BASIS FOR TESTING FOR THIS
;	ERRONEOUS USAGE. 
;
;
;	HOWEVER, THE AREA STATUS RECORD HAS ALREADY BEEN FORMATTED IN THE
;	BUFFER AND THE BUFFER HAS ALREADY BEEN FLAGGED AS UPDATED BEFORE
;	THIS TEST IS MADE. AS A RESULT, THIS EDIT WILL NOT UN-DO THE
;	UPDATE BEING DONE BY DBMEND. IT WILL ONLY AVISE THE USER THAT HE
;	HAS INCURRED A PROBLEM. AS A RESULT, HE WILL HAVE TO GO BACK AND
;	RE-CREATE THE AREA AS INDICATED IN THE EXPLANATION OF ERROR-STATUS
;	CODE XX43 IN THE DBMS-10/20 PROGRAMMERS MANUALS.
;
;CURE:
;
;	INSTALL EDIT 571 IN ORDER TO DO THE APPROPRIATE CHECKING AND TO
;	HAVE DBMEND GIVE THE ?MNDACS ERROR MESSAGE IN THIS SITUATION.
;
;	NOTE 1: THIS EDIT IS INSTALLED INTO THE DBSANY CODE WHICH IS USED
;	BY DBCS AND DBINFO, AS WELL AS DBMEND, FOR OPENING DATA BASE
;	AREAS. IT MAY BE INSTALLED INTO DBCS AND DBINFO WITH NO ILL
;	EFFECT BECAUSE DBCS AND DBINFO KNOW ABOUT RECORDS. BESIDES,
;	DBINFO ONLY OPENS THE DATA BASE IN USAGE-MODE EXCLUSIVE RETRIEVAL
;	AND DOES NOT UPDATE THE DATA BASE. ALSO, WHEN DBINFO ATTEMPTS
;	TO OPEN A NEWLY CREATED AREA, IT ALREADY GIVES THE ?INFAOE ERROR
;	MESSAGE.
;
;	NOTE 2: THIS EDIT ONLY CAUSES DBMEND TO PRODUCE THE ?MNDACS
;	ERROR MESSAGE WHEN IT GETS INVOLVED IN THE INITIALIZATION OF A
;	DATA BASE AREA. IT DOES NOT INHIBIT FURTHER ATTEMPTS TO OPEN
;	THE AREA, EVEN WITHIN THE SAME RUN OF DBMEND. THUS, IT IS
;	EXPECTED THAT THE USER WILL TAKE DIAGNOSTIC ACTION ON THE BASIS
;	OF THE APPEARANCE OF THE ERROR MESSAGE ITSELF.
;

;THE RECOMMENDED FILENAME FOR THIS EDIT IS 571.FIX.    THE LINES
