Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of ASMIDF for z/OS, z/VM and       *
  *                 z/VSE.                                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: ASMIDF is unable to support the         *
  *                      following instructions: CLRB, CLGRB,    *
  *                      CLRJ, CLGRJ, CLIB, CLGIB, CLIJ, CLGIJ   *
  *                      and their extended mnemonics.           *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF provided.                      *
  ****************************************************************
  When using IDF to single-step through the instructions CLRB,
  CLGRB, CLRJ, CLGRJ, CLIB, CLGIB, CLIJ and CLGIJ, IDF incorrectly
  steps through these instructions and may indicate that the
  program has terminated and returned control prematurely.
  

Problem conclusion

• ASMIDF has been modified to handle the branching of the
  instructions CLRB, CLGRB, CLRJ, CLGRJ, CLIB, CLGIB, CLIJ and
  CLGIJ and their extended mnemonics thus allowing IDF to
  correctly single-step through these instructions.
