Problem summary

• ****************************************************************
  * USERS AFFECTED: All Online Pointer Checker users of High     *
  *                 Performance Fast Path Utilities FP Online    *
  *                 Tools Version 3 Release 2 (FMID: H31A320).   *
  ****************************************************************
  * PROBLEM DESCRIPTION: 1. ABEND SB37 occurs when OPC runs with *
  *                         FULLSTEP=YES and DARxxxx data set is *
  *                         allocated dynamically.               *
  *                      2. FPX0059E message is issued when OPC  *
  *                         detects segment checksum error.      *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  1. OPC did not correctly specify the parameter to the DYNALLOC
     macro for DARxxxx data sets. Therefore data set was allocated
     with smaller space than OPC estimated.
  2. When OPC detects segment checksum error, OPC cannot make a
     correct local error record due to the incompleteness of local
     error record mapping macro.
  

Problem conclusion

• 1. OPC has been modified to set pointer to Text unit for
     DYNALLOC macro correctly.
  2. The location counter of local error record mapping macro was
     revised.
