PI07125: SERVICE FLOW PROCESS NOT RECEIVING DATA DUE TO GETTING STRING PROPAGATION IN SNA-VECTOR-DATA IN DFHMAVCP.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• We were making room in SNA-VECTOR-DATA to insert x'124040124040'
  and then increasing the overall length by 6.  However, because
  we were manipulating the same string (SNA-VECTOR-DATA), we were
  getting string propagation.  The solution was to build the
  string in a temporary area and then copy it back when complete
  into SNA-VECTOR-DATA which is a parameter that DFHMAFSO
  receives.
  .
  Here's a snippet of the code involved:
  .
  MOVE SNA-VECTOR-DATA(3:SNA-BUFFER-LENGTH)
    TO SNA-VECTOR-DATA(9:SNA-BUFFER-LENGTH)
  MOVE X'124040124040' TO SNA-VECTOR-DATA(3:6)
  ADD 6 TO SNA-BUFFER-LENGTH

  * PROBLEM DESCRIPTION: SEND MAP with ERASEAUP option may have  *
  *                      unpredictable results.                  *

  ****************************************************************
  A native application performed an EXEC CICS SEND MAP with the
  ERASEAUP ( erase all unprotected ) option. This option should
  erase INPUT fields on the map ready for user input but not
  erase INPUT fields if the application had placed values into
  those fields prior to the SEND MAP.
                                                                 .
  When the above application was modelled into a Service Flow,
  fields that had been updated by the application prior to the
  SEND MAP were also erased. Thus the behaviour of the application
  running natively and as a Service Flow were different.
                                                                 .
  Code in DFHMAVCP that processed the ERASEAUP option was not
  working as intended.
  

Problem conclusion

• DFHMAVCP has been modified to correctly process the ERASEAUP
  option on an EXEC CICS SEND MAP.
