Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IDF for z/OS, z/VM and z/VSE.   *
  ****************************************************************
  * PROBLEM DESCRIPTION: ASMIDF is unable to support the         *
  *                      following instructions:                 *
  *                      CRB, CGRB, CRJ, CGRJ, CIB, CGIB, CIJ,   *
  *                      CGIJ and their extended mnemonics.      *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF provided.                      *
  ****************************************************************
  When using IDF to single-step through the instructions CRB,
  CGRB, CRJ, CGRJ, CIB, CGIB, CIJ and CGIJ, IDF incorrectly steps
  through these instructions and may indicate that the program
  has terminated and return control prematurely.
  

Problem conclusion

• ASMIDF has been modified to correctly handle the branching of
  the instructions CRB, CGRB, CRJ, CGRJ, CIB, CGIB, CIJ and CGIJ
  and their extended mnemonics thus allowing IDF to correctly
  single-step through these instructions.
