Setting Save Response Buffer
If Save Response Buffer is:
Set to N, CLI de-allocates the buffer(s) and Request Context Block when DBCHCL is
called for the End Request function.
Set to Y, CLI saves one response buffer and saves the Request Context Block when DBCHCL
is called for the End Request function. If the saved buffer is too small for the next
request, the saved buffer is deleted and a new buffer of the required size is allocated.
