Thanks for all the input. Besides the fact that the application could conceivably have hundreds of thousands of session Vars in memory, I'm concerned about collision too.
I see no scope referencing in these Vars and see they are all 'common names'. I also see no routines to clear any vars after completion of an operation is over. Oh well. Robert B.
