  The failing instruction is a TM, 91 80 2009  with R2 containing
  an invalid address.  R2 was loaded using storage with residual
  data from previous use, so what shows up in R2 may vary. This
  are is defined as VOMP_PICKLIST.  R2 got loaded from R13+x'18C',
  and R13 is the stack address. This was supposed to be the
  VOMP_PTR address.
  .
  The preceding call to EYU0VOLP returned vold_EmptyTable (at
  R13+0190),
  so VOMP_PICKLIST should not have been referenced.

  * USERS AFFECTED: All CICSPlex SM V4R1M0 Users                 *
  ****************************************************************
  * PROBLEM DESCRIPTION:    You might observe abend ASRA / S0C4  *
  *                      in your WUI server when executing a     *
  *                      function which builds a Task Guide      *
  *                      view, if a parameter rendered in the    *
  *                      Task Guide is not valid for the action  *
  *                      being performed.  This usually occurs   *
  *                      where the same Task Guide is used for   *
  *                      more than one action (for example,      *
  *                      CREATE and UPDATE for BAS resources).   *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all Web User Interface (WUI) servers   *
  *                 must be recycled to pick up the new code.    *
  *                 Note that servers do not need to be brought  *
  *                 down and restarted at the same time.         *
  ****************************************************************
     Module EYU0VHDA (VHDA - WUI Render Attributes and Keywords)
  is called to render attribute and parameter entry lines for a
  Task Guide.  VHDA calls EYU0VOLA (VOLA - WUI Attribute Search)
  or EYU0VOLP (VOLP - WUI Parameter Search) to retrieve a pointer
  to the attribute or parameter descriptor for the element being
  rendered.  If the attribute or parameter is not defined, no
  pointer is returned and VHDA then uses residual data from the
  stack frame as a pointer to the desired attribute or parameter
  descriptor.  This could result in an abend ASRA / S0C4 if the
  presumed address references non-existent storage or storage
  which is fetch protected.
  

Problem conclusion

• EYU0VHDA was modified to access the returned attribute or
  parameter descriptor only if EYU0VOLA or EYU0VOLP returns
  a code of VOLD_OK.
