	countchar.x:  RPCGEN program for example with two procedures
                  served by the same RPC server.

                  Note also that program COUNTALLCHARS demonstrates
                  passing a linked list from the server back to the
                  client.

	Description: 

          COUNTCHAR counts the number of occurrences of a given
		  character in a passed character string.  The parameter passed
		  to countchar is a pointer to a structure that contains two
		  strings:

			1) the character string to be searched,
			2) the character to be searched for.

          COUNTALLCHARS returns a linked list of counts for all characters
          that occurred the string, each entry containg the character and
          its associated occurrence count.  The parameter is a pointer
          to the string.
