Error description

• The client has an application that issues an EXEC CICS

  because register 1 contains zero. This is in routine
  create_data_entry.

  ****************************************************************
  CICS is called to convert JSON data to application data either
  as a result of a web service call or use of EXEC CICS TRANSFORM
  JSONTODATA.  The JSON data contains a string which contains an
  escape character at least 2048 characters into the string.  This
  exposes defective logic in DFHPIJP1 which is reading low core
  and results in an 0C4.
  

Problem conclusion

• DFHPIJP1 parser has been changed to avoid addressing low-core.
