Local fix

• DFHWBCLI is still using 31-bit addresses and lengths so
  when it populates the WBCL_BODY parameter it copies data
  into the wrong offsets.  This causes the actual body data
  to not be sent.
  .
  Web Client Applications should really be updated to use EXEC
  CICS WEB commands.  If the applications were using the WEB
  API commands then they would not be exposed to this problem.

  * PROBLEM DESCRIPTION: Request body can not get properly sent  *
  *                      out when using DFHWBCLI to send a POST  *
  *                      request.                                *
  ****************************************************************
  An application is using DFHWBCLI to send a POST request with a
  request body to a remote server. The address and length of the
  request body which are supplied by DFHWBCLI are 31-bit pointer
  and length, they are copied into internal variables as 31-bit
  values. But the DFHWBCL parameter BODY is a buffer made up of
  64-bit values. This results in the values ending up in the wrong
  fields in the DFHWBCL parameter BODY when DFHWBCL WRITE_REQUEST
  call is made. Accordingly, the request body does not get sent.
  

Problem conclusion

• DFHWBCL has been changed to make sure the request body can be
  properly copied from DFHWBCLI to DFHWBCL work area and sent.
