Error description

  • DFHWBBMS loops on data with an escaped character. This is
    unexpected however DFHWBBMS uses the variable M for the loop
    amount instead of J. M is not initialized and if it happens
    to contain zero then there is an infinite loop.
    Additional Symptoms:  Task issuing RECEIVE_MAP
    Receives DFHWB0004 A possible loop has been detected at
    offset X'FFFF' in module DFHWBBMS.
    Runaway.  Could also receive DFHSM0002
    x'0D0C' Severe Error.  Invalid_freemain_address.

    DFHWBBMS was being driven and was processing a symbol string as
    part of a 3270 web bridge request.  The symbol string contained
    a symbol name that ended in an escaped '#' character ( %23 ).
    This caused an OTHERWISE clause within loop Symbol_scan to
    be driven.  This OTHERWISE clause used an uninitialised
    control variable which caused the Symbol_scan do while to loop
    repeatedly.  This apar also addresses the problem reported by
    PI45758 ( incorrectly formatted web page ) which will be closed
    as a DUP of this apar.

Problem conclusion

  • DFHWBBMS has been modified to process the escaped '#' at the end
    of a symbol name correctly. It also addresses the problem of
    an incorrectly formatted web page reported by apar PI45758
    ( which will be closed as a DUP of this apar ).
