  2607. * ONCE AGAIN, THE CCHHR ADDRESS USED MUST BE THE ADDRESS 02602000

  2611. * SEQUENTIAL READING. NOW, WITH EVERY READ, WHETHER RANDOM OR 02606000
  2612. * SEQUENTIAL, THERE ARE TWO CCHHR ADDRESSES INVOLVED. 02607000
  2613. * FIRST, THERE IS THE ADDRESS OF THE PRIOR RECORD, USED 02608000
  2614. * FOR THE SEARCH, AND SECOND, THERE IS THE ADDRESS OF THE 02609000
  2615. * CURRENT RECORD, THAT IS READ FROM THE COUNT FIELD. 02610000
  2616. * WHEN EREP DOES RANDOM READING IT COULD USE THE FIRST 02611000
  2617. * ADDRESS AS A SEARCH ADDRESS, THE SAME AS IT DID DURING 02612000
  2618. * THE SEQUENTIAL READING, BUT IT DOESN'T. INSTEAD IT USES 02613000
  2619. * THE SECOND ADDRESS, THE ONE FROM THE COUNT FIELD OF THE 02614000
  2620. * RECORD ACTUALLY READ. THIS SECOND ADDRESS IS THE ONE 02615000
  2621. * THAT EREP SAVES IN A TABLE DURING THE SEQUENTIAL READING. 02616000
  2622. * BUT SINCE THIS IS THE ADDRESS OF THE DESIRED RECORD (AND 02617000
  2623. * NOT THE ADDRESS OF THE PRECEEDING RECORD AS REQUIRED BY 02618000
  2624. * THE CHANNEL PROGRAM), EREP HAS TO MODIFY THE ADDRESSES 02619000
  2625. * THAT IT PULLS OUT OF THE TABLE BEFORE IT CAN USE THEM IN 02620000
  2626. * THE CHANNEL PROGRAM. THIS MODIFICATION CONSISTS SIMPLY 02621000

  2628. * DATA RECORDS ARE NUMBERED 1 THRU N, THE DECREMENTED VALUE 02623000
  2629. * OF R HAS THE RANGE 0 THRU (N-1). SEARCHING FOR A RECORD 0 02624000

  2717. * IN HANDLING THE EXCP'S THAT EREP ISSUES TO READ ERROR RECORDS 02712000
  2718. * SEQUENTIALLY FROM SYS1.LOGREC, WE WILL BE CALLING DMSREA TO 02713000
  2719. * READ ONE RECORD AT A TIME FROM THE VM/370 ERROR CYLINDERS. 02714000
  2720. * BUT WE WILL ALWAYS HAVE TO STAY ONE RECORD AHEAD OF THE ONE 02715000
  2721. * CURRENTLY BEING REQUESTED BY THE EXCP. THE REASON FOR 02716000
  2722. * KEEPING ONE RECORD AHEAD IS THAT DURING THE SIMULATION OF 02717000
  2723. * THE CURRENT EXCP WE HAVE TO KNOW WHETHER OR NOT THERE WILL 02718000
  2724. * BE A RECORD FOR THE NEXT EXCP. WE HAVE TO KNOW WHETHER OR 02719000
  2725. * NOT THERE WILL BE A NEXT RECORD BECAUSE OF THE NATURE OF THE 02720000
  2726. * CHANNEL PROGRAM AND BECAUSE OF THE METHOD EREP USES TO 02721000
  2727. * DETECT THE (LOGICAL) END OF FILE. THE CHANNEL PROGRAM 02722000
  2728. * RETURNS THE CCHHR ADDRESS OF THE CURRENT RECORD AFTER EACH 02723000
  2729. * EXCP. NOW IF THE CURRENT RECORD HAPPENS TO BE THE LAST 02724000
  2730. * RECORD, ITS RETURNED CCHHR ADDRESS SHOULD MATCH THE CCHHR 02725000
  2731. * ADDRESS (OF ALL X'FF') IN THE 'HDRLAST' FIELD OF THE 02726000
  2732. * (SIMULATED) HEADER (AND IN FACT EREP LOOKS FOR THIS MATCH). 02727000
  2733. * THEREFORE IN THE CASE OF THE LAST RECORD, THE SIMULATED 02728000
  2734. * CCHHR VALUE RETURNED AFTER THE EXCP MUST BE 02729000
  2735. * THE ALL X'FF' VALUE FOUND IN 'HDRLAST'. AND IN 02730000
  2736. * SIMULATING THE EXCP, THE ONLY WAY WE HAVE OF KNOWING WHETHER 02731000
  2737. * OR NOT TO RETURN THE 'HDRLAST' VALUE AS THE RETURNED CCHHR 02732000
  2738. * IS TO KNOW WHETHER OR NOT THE VM/370 ERROR CYLINDERS CONTAIN 02733000
  2739. * ANOTHER RECORD. THIS WE DETERMINE BY READING ONE RECORD 02734000
  2740. * AHEAD. (NOTE: THE RECORD READ AHEAD CAN REMAIN IN THE 02735000
  2741. * I/O BUFFER OF DMSREA UNTIL IT IS NEEDED FOR THE NEXT EXCP. 02736000
  2742. * DMSREA DOES NOT RETURN DATA TO A BUFFER OF THE CALLER; 02737000
  2743. * INSTEAD IT JUST RETURNS A POINTER TO THE DATA SO THE 02738000
  2744. * CALLER CAN GET IT ANYTIME PRIOR TO HIS NEXT CALL.) 02739000
  2745. * 02740000
  2746. * IN THE CASE OF ALL OTHER ERROR RECORDS (I.E., ALL BUT THE 02741000
  2747. * LAST), THE CCHHR VALUE RETURNED TO EREP WITH THE RECORD IS 02742000
  2748. * RATHER ARBITRARY AS FAR AS EREP IS CONCERNED; EREP NEVER 02743000
  2749. * LOOKS AT IT EXCEPT TO COMPARE IT WITH 'HDRLAST' IN THE 02744000
  2750. * CASE OF SEQUENTIAL I/O, OR TO DECREMENT THE R FIELD BY 02745000
  2751. * ONE IN THE CASE OF RANDOM I/O. 02746000
  2752. * THE ARBITRARY VALUE WE WILL USE IN THE SIMULATION WILL 02747000

  2754. * 02749000
  2755. * IN THE CASE OF SEQUENTIAL I/O, THE CCB0R VALUE THAT WE 02750000
  2756. * PASS TO EREP ON ONE READ IS PASSED BACK TO US BY EREP ON 02751000
  2757. * THE NEXT READ AS THE SEARCH ADDRESS. NOTE: WHEN WE SEE 02752000
  2758. * IT AS A SEARCH ADDRESS WE HAVE TO ADD ONE TO IT BEFORE 02753000

  2766. * ALL SUBSEQUENT EXCP'S SHOULD BE ATTEMPTING RANDOM READS. 02761000
  2767. * WE WILL NO LONGER KEEP ONE RECORD AHEAD. EREP WILL DO 02762000
  2768. * RANDOM READING USING THE RECORD ADDRESSES THAT WERE SEEN 02763000

  2770. * ADDRESSES (CCHHR) SEEN BY EREP DURING THE SEQUENTIAL READING 02765000
  2771. * ARE REALLY IN THE CCB0R FORMAT RECOGNIZED BY DMSREA, SO 02766000
  2772. * WHEN EREP PASSES THEM BACK TO US NOW DURING THE RANDOM 02767000

  2776. * DMSREA, WE MUST FIRST INCREMENT THE R BYTE BY ONE SINCE EREP 02771000
  2777. * HAS DECREMENTED THE R BYTE TO MAKE IT A SEARCH ADDRESS 02772000
  2778. * RATHER THAN THE DESIRED-RECORD-ADDRESS WHICH DMSREA GOES 02773000
  2779. * BY.) THERE IS ONE EXCEPTION WHERE THE CCHHR ADDRESS PASSED 02774000
  2780. * BY EREP IS NOT IN THE DESIRED CCB0R FORMAT. THIS OCCURS 02775000
  2781. * IF EREP TRIES TO READ THE VERY LAST ERROR RECORD BECAUSE 02776000

  2784. * SO DURING THE RANDOM READING WE WILL WATCH THE ADDRESSES 02779000
  2785. * THAT EREP PASSES AND IF WE SEE THE ALL X'FF' ADDRESS, WE 02780000
  2786. * WILL SUBSTITUTE THE PROPER CCB0R ADDRESS IN PLACE OF IT 02781000

  2792. * 02787000
  2793. * DMSREA CAN RETURN SEVERAL INDICATIONS OF UNUSUAL SITUATIONS: 02788000
  2794. * (1) END-OF-FILE, (2) EMPTY 4K BLOCK, (3) I/O ERROR READING 02789000
  2795. * A 4K BLOCK. 02790000
  2796. * 02791000
  2797. * WE CAN HAND I/O ERRORS OVER TO EREP BY SIMPLY 'POST'ING 02792000
  2798. * AN ERROR COMPLETION CODE IN THE EXCP'S ECB. BUT IT APPEARS 02793000
  2799. * THAT EREP WILL THEN DIE IMMEDIATELY, SO WE WANT TO AVOID 02794000
  2800. * POSTING ERRORS BACK TO EREP WHENEVER POSSIBLE. WITH THAT 02795000
  2801. * IN MIND, DMSREA IS DESIGNED TO SKIP PAST TROUBLESOME BLOCKS 02796000
  2802. * TO THE NEXT READABLE RECORD. DURING THE SEQUENTIAL 02797000
  2803. * READING WE CAN EXPECT DMSREA TO SOMETIMES SEE (AND PASS 02798000
  2804. * OVER) A BAD BLOCK. IT GIVES US BACK THE NEXT AVAILABLE 02799000
  2805. * RECORD, ALONG WITH A CODE IN R15 INDICATING A BAD BLOCK 02800000
  2806. * WAS SKIPPED. DURING THE SEQUENTIAL READING WE EXPECT 02801000
  2807. * THAT THIS MAY HAPPEN AND WE IGNORE IT. BUT DURING THE 02802000
  2808. * RANDOM READING, WE DO NOT EXPECT ANY ATTEMPTS TO READ 02803000
  2809. * FROM ANY BAD BLOCK BECAUSE EREP SHOULD ONLY ATTEMPT TO 02804000
  2810. * READ FROM BLOCKS THAT IT SAW DURING THE SEQUENTIAL READING 02805000
  2811. * AND DURING THE SEQUENTIAL READING DMSREA SKIPPED OVER 02806000
  2812. * ALL BAD BLOCKS WITHOUT SHOWING EREP ANY RECORDS FROM THEM. 02807000
  2813. * SO IF WE DO GET AN INDICATION OF A BAD BLOCK DURING THE 02808000
  2814. * RANDOM READING, IT MEANS THE BLOCK WENT BAD SOME TIME AFTER 02809000
  2815. * THE SEQUENTIAL READING. IN THIS CASE WE MUST POST IT BACK 02810000
  2816. * TO EREP AS AN I/O ERROR; WE CAN'T HIDE THE BAD RECORD 02811000
  2817. * BECAUSE EREP HAS ALREADY SEEN IT DURING THE SEQUENTIAL 02812000
  2818. * READING. 02813000
  2819. * 02814000
  2820. * NORMALLY THE 'FIRST' AND 'SECOND' (OR SEARCHED FOR AND 02815000
  2821. * DESIRED) RECORD ADDRESSES ARE TWO LOGICALLY ADJACENT RECORDS. 02816000
  2822. * HOWEVER SINCE DMSREA WILL SKIP OVER ANY TROUBLESOME BLOCKS, 02817000
  2823. * SOME INACCESSIBLE RECORDS MAY LIE BETWEEN THE RECORD HAVING 02818000
  2824. * THE FIRST ADDRESS (SEARCH ADDRESS) AND THE RECORD HAVING 02819000
  2825. * THE SECOND ADDRESS (ADDRESS OF THE RECORD THAT IS READ). 02820000
  2826. * IT WAS MENTIONED EARLIER THAT DURING THE RANDOM READING, 02821000
  2827. * EREP SUBTRACTS ONE FROM THE R FIELD OF THE 'SECOND' 02822000
  2828. * ADDRESS TO COMPUTE A SEARCH ADDRESS. NORMALLY THIS GIVES 02823000
  2829. * THE SAME SEARCH ADDRESS AS WAS USED DURING THE SEQUENTIAL 02824000
  2830. * READING. BUT WHERE INACCESSIBLE RECORDS WERE SKIPPED 02825000
  2831. * OVER IT DOES NOT. IN THIS CASE THE COMPUTED SEARCH ADDRESS 02826000
  2832. * STARTS AT THE FAR SIDE OF THE BAD AREA, SO DMSREA DOES 02827000
  2833. * NOT HAVE TO SKIP OVER THE BAD BLOCKS TO FIND THE DESIRED 02828000
  2834. * RECORD; INSTEAD DMSREA IS SENT DIRECTLY TO THE GOOD RECORD. 02829000
