ABSTRACT OF PROBLEM
___________________
TPFDF  recoup  corrections:  1)Entries missing from ZRECP LOG 2)
OPR-DB0102 on ZRECP LOG 3) Inactive groups may be  shown  to  be
active  in  the  log  display  4)  Selective  recoup  can't find
fileaddr's in online errlog.
 
COMMENTS ON PROBLEM
___________________
 
1.  Some TPFDF record IDs that are processed may not show up  in
    the  TPFDF  recoup log.   This is due to a timing problem in
    segment BRC8 where two ECBs can attempt to  write  the  same
    LREC  in  the recoup log file, GR0ZSR.  If this happens, the
    second entry will overwrite the contents of the first entry.
 
2.  An OPR-IDB0102 may occur if the ZRECP LOG command is entered
    with parameters that are not part of the valid syntax of the
    command.  For example, ZRECP LOG *.    This  occurs  because
    segment  BRC0  does  not  parse  the  command  properly  and
    attempts  to  interpret  any  extraneous  parameters  as   a
    processor ID.
 
3.  If  a  ZRECP  LOG  command  is entered while TPFDF recoup is
    active, the entry will indicate which TPFDF record  IDs  are
    currently  being  processed.    However,  if  the command is
    entered at the end of phase I when recoup  is  deferring  to
    correct  fixed  errors,  log  display  will indicate several
    record IDs are currently active  when  they  aren't.    Some
    entries  also contain invalid record IDs.  This is caused by
    an invalid check for active recoup restart areas in BRC0.
 
4.  If a fixed error is found during TPFDF recoup, recoup defers
    to allow the user to correct the error.   If the  user  per-
    forms  a  selective  recoup  to attempt to process the fixed
    error record, recoup will generate  a  BKA10003A  NO  ERRORS
    WITH  THAT  ID  warning that the fixed error to be corrected
    can't be found in the online  error  log,  even  though  the
    error really did occur.
 
SOLUTION
________
 
1.  Segment  BRC8  has  been  updated  to increment LREC counter
    BK0LRC before doing the DBADD to  guarantee  unique  values.
    The  #STPF  macro was also changed to use a compare and swap
    mechanism.
 
2.  Segment BRC0 has been updated to ignore  extraneous  parame-
    ters on the ZRECP LOG command.
 
3.  Segment BRC0 has also been updated to test for active groups
    properly.   Furthermore, active record IDs are now indicated
    with the text "IN PROGRESS" instead of "ACTIVERECP".
 
4.  Segment BRC2 has been updated such that when a  fixed  error
    entry  is written to the online error log, it is marked as a
    fixed error so that it can be found if an attempt is made to
    correct the error.
 
5.  Finally, segment GR0ZSR has been updated such that the start
    time field GR0ZTRC is properly split into the  4-byte  start
    time  and 4-byte end time.  Segment BRC0 has been updated to
    use the appropriate new labels.
