  Sample security exit CSQ4BCX3 uses function DBGPRINTF() that
  calls CSQXCTRC to generate trace text in the CHIN trace. Macro
  CSQXTRC calls CSQXFIND to locate a control block and it expects
  R6 to be set with the address of xEB control block but this
  value is not set causing the 0C4 abend.
  

Problem conclusion

• CSQXFIND has been changed to set R6 with the address of xEB.
