  in CICS.
  

Local fix

• Use the COBOL compiler option trunc(bin)

  ****************************************************************
  The module ELACOMC is doing pointer arithmetic for
  performance reasons. The module was erroneously
   compiled  with trunc(std) instead of trunc(bin).
  This causes the pic s9(9) comp-4 field to
   be truncated producing an invalid address.
  The abend occurs because of this bad address.
  

Problem conclusion

• The module ELACOMC was recompiled with trunc(bin)
