                   Discriminated Union Example 
 
    FILE:       unionp.c 
 
    PURPOSE:    Remote procedures that are linked with the server 
                side of RPC distributed application 
 
    FUNCTIONS:  UnionParamProc()  - union, discriminant are parameters 
                UnionStructProc() - union, discriminant in structure 
 
    COMMENTS:   This distributed application illustrates distriminated 
                union.
