;2001 DE-IMPLEMENT /Q SWITCH. MAKE /F DO A /Q IF STR IS OVER QUOTA
;2002 FIX INCORRECT AC REFERENCE IN PISYS UUO FROM T1 TO T4
;2003 FIX AN EDITTING ERROR IN EDIT 2001
;2004 MAKE THE BATCH DELETION ALGORITM UNDERSTAND NQC FILES AND ALSO
; RECOVER MORE GRACEFULLY FROM SOME ERROR CONDITIONS
;2005 IF ACCOUNTING SYSTEM FAILURE IN A BATCH JOB, NOTIFY THE OPR AND
; LOG THE JOB OFF ANYWAY
;2006 MAKE THIS VERSION 101, NOVEMMBER, 1975
;2007 CLEAR L.USE BEFORE DOING QUOTA CHECKING ON EACH STRUCTURE
;2010 ENABLE FOR CONTROL-C INTERRUPTS, AND LET THE USER GET OUT
; WHILE WE ARE COMMAND SCANNING
;2011 IMPLEMENT /T TO DELETE JOB'S UNPROTECTED TEMP FILES
;2012 ADD A ROUTINE CALLED "TYPSTR" TO TYPE OUT THE CURRENT FILE-STRUCTURE
;2013 REMOVE /T SWITCH AND MAKE TMP FILE DELETION AUTOMATIC
;2014 MOVE "OTHER JOBS SAME PPN" MESSAGE TO THE BEGINNING RATHER
; THAN PART OF THE SUMMARY MESSAGE
;2015 DO A CLRBFI UPON FINISHING COMMAND-SCAN
;2016 ADD .BLI TO IMPORT TABLE IN LGTBA
;2017 DO A CLRBFI (EDIT 2015) IFF BATCH JOB
;2020 IF WE TRY TO DELETE A FILE BECAUSE A STRUCTURE IS OVER QUOTA
; ON /B, AND THE DELETE FAILS, MAKE HIS QUOTA LOOK BIGGER BY
; THE SIZE OF THE FILE UNLESS THE ERROR WAS PROTECTION FAILURE
; (SEE MOTIVATION SECTION FOR FURTHER INFO).
;2021 IF DAEMON IS NOT RUNNING, A USER CAN LOG OUT IF HE
; SAYS K/B BECAUSE LOCATION L.BJOB WAS BEING TIMESHARED.
;2022 RATHER THAN DELETING TEMP FILES ON A STRUCTURE BY STRUCTURE
; BASIS, DELETE THEM ALL AT ONCE.
;2023 MAKE THIS VERSION 102 (NOTE: VERSION 101 WAS NEVER RELEASED).
;2024 FIX SOME MINOR PROBLEMS AND DO SOME CODE CLEANUP.
;2025 TRY HARD TO DELETE EMPTY SFDS IN /B ALGORITHM.
;;FIRST FIELD-TEST RELEASE OF GALAXY VERSION 2, JANUARY 1977
;;SECOND FIELD-TEST RELEASE OF GALAXY VERSION 2, MARCH 1977
;2026 TMP FILES WEREN'T ALWAYS DELETED DUE TO FUZZY CODING IN THE
; DELTMP ROUTINE (QAR #30).
;2027 IF LOGOUT DELETED TMP FILES, SOME STRUCTURES WERE NOT
; QUOTA CHECKED AND USERS HAD TO RECOMP NEXT TIME THEY LOGGED IN.
;2030 IF LOOKUP AT LGTRC1+3 FAILS, DON'T HALT. SET T1 TO ZERO.
;2031 IN DEFINITION OF FIRMAC (IN .LGTBA) "X LS?,777700" DELETES LISP
; SOURCE FILES (*.LSP FILES.) CHANGE TO DELETE ALL *.LSD, *.LSQ AND
; *.LST FILES.
;2032 MAKE CCIINB POINT TO L.PSIB+4, NOT L.PSIB SINCE DETINB POINTS THERE.
;2033 WHEN AN ATTACH OR A DETACH IS TRAPPED AT PSIDET, DO A CLRBFO TO
; CLEAR THE OUTPUT BUFFER TO AVOID GETTING STUCK IN TO STATE.
;2034 MAKE IT IGNORE ANY CHARACTERS TO THE RIGHT OF A SEMICOLON
; (COMMENTS)
;2035 COMPLETE EDIT 2034 BY ALLOWING COMMENTS TO BEGIN WITH "!"
;2036 SPR # 10-25857 WCL 13-Jul-78
; Change EXP initialization of F.FUN and F.HDR to BLOCK's
;2037 SPR 10-26842 KPY 18-OCT-78
; DO A CLRBFI (2017) FOR PTYs ALSO
;2040 SPR 10-26925 KPY 6-NOV-78
; IF LOGOUT IS RUN WITHOUT PRIVILEGES, ISSUE AN ERROR MESSAGE
; AND EXIT (DOES NOT APPLY TO BATCH AND DETACHED JOBS)
;2041 SPR 10-26900 KPY 7-NOV-78
; USE L.NOW WHEN REPORTING SUMMARY TO BE CONSISTANT WITH DATE/TIME
; REPORTED IN FACT FILE
;
;2042 Check for a job having eternal ENQ. locks set and exit (if a
; timesharing user) or detach job (if a Batch user).
;
;2043 Add a call to CLRLOK at T$OUF so the UFD interlock is cleared
; before exit if OPEN UUO fails due to funny space full condition.
;
;2044 Report other users logged in like LOGIN does.
;
;2045 Edit 2042 attempted to detach a Batch job if there were any
; outstanding eternal ENQ. locks. It was a bad idea. Hang the
; Batch stream instead.
;
;2046 Add a flag (F.FLAG) to determine if FACT file entries should be
; made. This is in preparation for converting to USAGE accounting.
; *** Note ***
; FACT file code will be removed once USAGE accounting is fully
; implemented.
;
;2047 Attempt to fix the problem of not deleting all files that should be
; deleted when KJOB/BATCH is typed.
;
;2050 (SPR 10-29858 / RKB / 26-Aug-80) Add the DBS filename extension
; to the IMPORT table.
;
;2051 Add some more extensions: R16, R36, and PAS.
;
;2052 Remove edit 2047 since it didn't work right. To correctly fix the
; the problem, WILD need some work.
;
;2053 Clear any time limit so that batch jobs won't die in the middle of
; logging out.
;
;2054 Make debugging easier. Don't check for JACCT privs. Don't delete TMPCORr
; files. Don't empty search list. Allow control-C to do their thing.
;
;2055 Incorporate missing HOSS edit #2042 that defines WLDARG scan block
; length correctly.
;
;2056 Incorporate missing HOSS edit #2051 that added the INI extension to the
; list of 'important' files.
;
;2057 In the batch deletion algorithm, delete zero block files first.
;
;2060 Clear the time limit after command scanning is done so a batch user
; can't type KJOB/HELP to give himself infinite time and continue his
; job. Remove the 10 line-feeds following the summary text so that
; any tape statistics that get reported when jobs logout will appear
; close to the summary text.
;
;2061 Don't type "Files deleted:" before the RENAME UUO is attempted. If
; it fails, print a warning.
;
;2062 If we can't log the guy out and there's no operator on duty, don't
; tell him to call the operator.
;
;2063 If RESCAN fails and the job is a batch job, we might have been invoked
; by a forced KJOB command, so default to /BATCH.
;
;2064 A few more extensions for the FIRMAC and IMPMAC macros.
;
;2065 Make statistics typed by LOGOUT match those produced by the ACTDAE.
;
;2066 Always type flag LGTLQE errors with a question mark. BATCON
; doesn't depend on getting the %. BATCON %105(5000) needs this
; for KSYS processing.
;
;2067 Change DELTMP to use a FILOP. delete so FILDAE protected files get
; handled in the proper fashion.
;
; Start version 103 for 7.03
;
;2100 Turn off FACT file support by removing code.
;
;2101 Add SCAN switch scanning to get SWITCH.INI support.
;
;2102 Add the /HANGUP switch to hang up dataset lines. Useful for
; MICOM lines and other dataset look-a-likes.
;
;2103 Change the name of /HANGUP to /DISCONNECT, since this function
; works for all types of lines (DATASET, NRT, LAT, etc.).
;
;2104 Make NRT, CTERM, and LAT lines automatically disconnect by default.
; Set path to [,] just after deleting TMP files to insure SFDs
; may be deleted.
;
;2105 Do copyrights.
;
;2106 Add missing angle brackets in DISC macro definition to cause more
; than one entry in DISTAB to be built.
;
;2107 Massive clean-up, revise to use UFDSET.
;
;2110 Move call to GTTABS above call to .ISCAN to prevent jobs from
; getting logged-in under [0,0] if user types bad guide word or
; makes a similar .SCAN syntax error.
;
;2111 Inform LOGOUT it can be run without the user having been logged
; in previously (see MCO 12640). Key off the job's logged-in time
; being zero to decide whether to perform full LOGOUT functions.
; Use new TRMOP. function .TODNT to disconnect terminal (.TODSF
; has reverted to 7.02 functionality). Still do .TODSF, but add
; .TODNT after .TODSF.
;
;2112 Add "BYE" command to always force a DISCONNECT.
;
;2113 Zero TMPCOR before romping through the delete code.
SUBTTL Motivation for major functional changes
;2011 THE FACILITY TO DELETE A JOB'S TEMP FILES WAS ADDED DUE TO
; A LARGE NUMBER OF USER REQUESTS FOR SUCH A FACILITY.
;2013 THE DECISION TO MAKE EDIT 2011 SWITCHABLE WAS TO AVOID THE
; EXTRA DISK OVERHEAD UNLESS THE USER EXPLICITLY REQUESTS IT.
; IT WAS THEN REALIZED THAT THE OVERHEAD IS MINIMAL SINCE:
; 1) THE JOB IS LOGGED IN
; 2) THE UFD HAS ALREADY BEEN LOOKED-UP OR IS ABOUT
; TO BE
; SO THE OVERHEAD CONSISTS SOLELY OF READING THE UFD AS DATA
; WHICH IS MINIMAL.
;2020 IF THE DELETE OF A FILE FAILS, THE PROBABLE REASON IS THAT
; IT IS THE BATCH LOG FILE WHICH IS STILL OPEN BY BATCON.
; THIS FILE CANNOT BE TREATED AS NON-EXISTANT SINCE LOGOUT
; WILL THEN SET RIBUSD WRONG, SO BY INTERNALLY CONSIDERING
; HIS QUOTA TO BE THAT MUCH BIGGER, WE WILL AVOID DELETING
; OTHER FILES SIMPLY BECAUSE THE LOG FILE IS LARGE. IT WILL
; STILL BE COUNTED AGAINST HIS QUOTA ON FUTURE LOGINS SO
; IF THE BATCH SYSTEM DOESN'T DELETE THE LOG AFTER ITS
; PRINTED, IT WILL BE GOTTEN THE NEXT TIME HE LOGS OFF.
;2107 CHANGE LOGOUT TO USE UFDSET SO ALL UFD MANIPULATORS ARE
; CONSISTENT (LOGIN, LOGOUT, PULSAR).
;2111 KJOB/DISCONNECT IS A GREAT IDEA BUT ONLY WORKS IF THE JOB
; WAS LOGGED IN WHEN THE COMMAND WAS TYPED. CHANGE THE MONITOR
; SO IT ALWAYS INVOKES LOGOUT ON A "KJOB" COMMAND SO LOGOUT CAN
; LET USERS TYPE "KJOB/D" WHEN NOT LOGGED IN.
SUBTTL Debugging patch for the monitor
;THIS PATCH WILL ALLOW YOU TO DEBUG LOGOUT UNDER NORMAL TIMESHARING.
;THE PATCH IS EXECUTED VIA FILDDT AND CAUSES YOUR TERMINAL TO RUN
;LOGOUT FROM HAKSTR/HAKPPN WHILE ALL OTHER TERMINALS USE SYSPPN.
;NOTE THAT THE "$" ARE DOLLAR SIGNS. BEFORE EDITTING THIS PATCH OUT
;AND APPLYING WITH FILDDT, CHANGE THE DOLLAR SIGNS TO ESCAPES.
;THIS PATCH HAS BEEN TESTED UNDER THE 7.03 MONITOR. IT WILL NOT WORK
;WITH PREVIOUS MONITORS.

;.LGTSA is called first with the PPN and file-structure name

;In addition, a routine .LGTSE is provided to read *.EXT
