SET219A
* =======================================================
* Process ........: SET_219
* Function .......: SET219A
* Created on .....: 7th November, 2001
* Description ....: Caller example -> Calculator
* Version.........: 1
*
* Full Description:
*
* This function is a simple example of how SET219Y can
* be used to manage calls to functions on remote systems.
*
* In this case SET219A acts as a very simple calculator.
*
* It requests input of 2 numbers and passes the values to
* function SET219B which sums the numbers and sends back
* the result.
*
* A simple name is also passed to the server, reversed
* and sent back again to demonstrate how alphanumeric
* values are sent between systems.
*
* While the processing involved here is trivial, SET219A
* and SET219B together demonstrate the essentials of
* parameter passing between RDML functions running on
* different systems.
