    ****************************************************************
    When using CEOS or CEMS to browse a report, RCF (DFHEMSBR)
    reads the records from POWER to build up the screen, but also
    writes the records for each screen to a cache buffer. Record
    types of MCC Block data check (X'73'), MCC Allow data check
    (X'7B') and MCC no-op (X'03') are excluded from the cache and
    are also ignored when building up the screen. In this case
    the report contained the following sequence of control
    characters: X'01' (print/nospace), X'73' (MCC Block data check)
    and X'0B' (space one line immediately).
    If a print/nospace print record is immediately followed by a
    print line with an immediate space MCC control character
    DFHEMSBR decrements the number of lines spaced by 1. The
    presence of the X'73' record between the print/nospace
    and the immediate space record caused DFHEMSBR to
    incorrectly not decrement the number of lines spaced,
    resulting in an incorrect blank line on the screen.
    If the user then scrolls right, DFHEMSBR reads the records
    from the cache. The cache does not include the X'73' record
    so the X'01' record is now followed by a X'0B' record and
    the line number is correctly decremented.
    This means that the number of lines available in the cache
    is one less that the number of lines originally displayed.
    So when reading the final line for the display from the
    cache, DFHEMSBR reads residual data and picks up a large
    record length (X'C840'). This length is added to the cumulative
    total length of data for the screen, resulting in a length
    which is greater than the maximum allowed on an EXEC CICS
    SEND command (decimal 32767) and an abend AEIV (LENGERR)
    occurs, followed by an abend APTM.
    Other unpredictable results may occur depending on the
    residual data in the cache.

Problem conclusion

  • DFHEMSBR had been altered to not set the indicator that
    results in the line count being decremented, for record types
    of X'03', X'73' or X'7B'.
