Problem summary

• ****************************************************************
  * USERS AFFECTED: All QMF for TSO/CICS V8.1 and V9.1 users     *
  *                 displaying reports formatted by forms with   *
  *                 fixed columns.                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Users displaying or showing a report    *
  *                      formatted by a form that uses fixed     *
  *                      columns or using a screen size that is  *
  *                      smaller than the report width can       *
  *                      experience an ABEND0C4 in DSQCDBUG at   *
  *                      offset x'C90'. This problem could       *
  *                      happen in interactive or batch.         *

  ****************************************************************
  User was running QMF commands through the QMF command interface
  (but this problem would not be limited to situations run through
  the command interface). QMF commands such as RUN QUERY, DISPLAY
  FORM and SHOW REPORT were issued.  The SHOW REPORT abended as
  the formatting of the specialized form was being performed.
  This problem would not be limited to the scenerio above. Any
  time a form formats a report where the report is wider than the
  screen size or fixed columns are being used, this problem could
  occur.
  *
  If a QMF trace is taken, the last entry prior to the abend
  would be 'DSQFBTXT:MOVED CHARACTER DATA'.  If no abend
  occurred but this problem is suspected, users can look at the
  QMF trace output for strings 'WRKCTTLP->ANYCHARS' and check
  for non EBCDIC characters.
  

Problem conclusion

• Module DSQFBTXT was using variable CURTXTWD to determine the
  length of the line to format.  CURTXTWD was not taking into
  account fixed column widths nor screen size so the length of the
  buffer being written to could be overrun.  An abend can occur
  if QMF does not own the storage past the buffer. DSQFBTXT
  was modified to make sure the buffer is not overrun.
