Thank you, I appreciate the extra detail, especially about the DTAQ.

Yet there is potential for a great amount of resources required for an implementation via TABLE [any database *FILE] as contrasted with other potential implementations including a simple space object such as a Data Area (DTAARA) or User Space (USRSPC), to store\update what is perhaps effectively just a few bytes; a pre-loaded Data Queue (DTAQ) is one of my favorites, as explicit locking is reduced to only when concurrently reloading the queue during run-time, but that might be generally avoided by having sufficiently filled the queue while the application was off-line. What is "better" really depends on what are the needs and what are the costs for the overall solution; system-wide, not just the app.
