@Vitaliy Serdtsev  Thank you. I still need a bit more clarification.
• In which namespace is ^IRIS.TempRSet located?
• Am I correct in assuming that this mechanism relies on Process Private Globals (similar to Robert’s option)? If not, how can I view the global values in the SMP?
• Does each “rs” value get stored directly in ^IRIS.TempRSet, or does each "rs" data have its own node within ^IRIS.TempRSet? If it saved in separate node, how a name for such a node can be determine?
• Are the stored data/nodes removed automatically, or do they require a manual KILL operation?

@Vitaliy SerdtsevPlease clarify the step "d rs.%Save()" above. Where is the data actually stored, and can it be viewed in the Management Portal?
