When developing RSK-based applications using PL/X, make sure that 
the service routines are declared to accept the Ptr_to_sblock
and Ptr_to_cblock paramaters as BYVALUE and not the default of
BYADDR. That is, use the following code fragment:
   SRVNAME: proc (ptr_to_sblock, ptr_to_cblock) options(........);
      .......
     declare srvname entry(pointer(31) byvalue, pointer(31) byvalue)
             external as ('SRVNAME');
Otherwise, very unpleaseant things can happen inside your server. :-)
This is mention inn the comments in the PL/X code example show in Figure
5 in the User's Guide.
