OA21710: CICS WEB RECEIVE. AKEA ABEND IN MODULE DFHEIWB - REXX INTERFACE REGRESSION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Further debugging revealed that on INC 49, the
  area allocated by REXX for the INTO area used the
  MAXLENGTH value, but on INC 50, it did not,
  allocating a smaller area, and causing overwriting
  when the data was received using the MAXLENGTH
  size. Looking at the REXX keyword tables in main
  storage in the dump, I see that for INC 50 the
  keywords TOCONTAINER and TOCHANNEL appear between
  the INTO keyword and the MAXLENGTH keyword and I

Problem summary

  * PROBLEM DESCRIPTION: Rexx exec caused abend 0C4 in DFHEIWB.  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  A Rexx exec performed the following command:
                                                                 .
  'CICS WEB RECEIVE INTO(RECEIVE.INDEX) MAXLENGTH(32767)'
                                                                 .
  This produced a RECEIVE area of length x'7FFF' at an address
  at (for example) x'10000000'.  However, at X'10000900' was
  the start of the parameter list of the CICS WEB RECEIVE
  call.  This huge overwrite of the plist manifested itself
  as an 0C4 in DFHEIWB.  The Rexx EXEC interface relied on a
  CICS convention that a length field was always the next keyword
  in the table after the keyword to which it applied, however,
  this convention had changed.  A similar problem may occur for
  other commands.

Problem conclusion

• The ARGBLD routine in CICCP023 has been amended and is now
  compatible with the table conventions used by CICS.
