Problem summary

****************************************************************
* USERS AFFECTED: All CICSPlex/SM V3R1M0 Users                 *
****************************************************************
* PROBLEM DESCRIPTION:    Your CMAS receives abend S0C4 at an  *
*                      unknown offset in CSECT MXB40(MXB45).   *
*                      The PSW points 12 (x'C') bytes beyond   *
*                      the address in R15.  The return address *
*                      in R14 points to MXB45+5BA.             *
****************************************************************
* RECOMMENDATION: After applying the PTF that resolves this    *
*                 APAR, all CMASes must be recycled to pick    *
*                 up the new code.  Note that the restarts     *
*                 do not need to be done at the same time,     *
*                 nor is it necessary to restart CPSM CASes.   *
****************************************************************
   Function MXB45 (DataMapMap) in module BBM0XB40 (MXB40 - Class
DataMap Function Package) calls a generated subroutine to copy
mapped data to a target buffer for further processing.  The
subroutine accepts a pointer to the target buffer, an array of
up to seven source buffer pointers, and the instance pointer of
a DataMap object containing up to seven Map entries.  The code
executes a Load Multiple operation to load the source pointer
array contents into registers R5 - R11.  If the source pointer
array actually contains less than seven slots (in CPSM it should
never contain more than one) and if the array is allocated at
the end of a page of storage, abend S0C4 may result as the Load
Multiple accesses storage beyond the end of the allocated page.

Problem conclusion

   Function DataMapCompile (MXB4A) in module BBM0XB40 was modi-
fied to set the number of registers loaded by the Load Multiple
according to the count of Map entries being processed, contained
in the private area of the DataMap object.

Comments

   Your CMAS receives abend S0C4 at an
unknown offset in CSECT MXB40(MXB45).
The PSW points 12 (x'C') bytes beyond
the address in R15.  The return address
in R14 points to MXB45+5BA.
