benryves, I understand your hesitation there; I assumed that was why you chose the flag-based option as a sort of pseudo program return value rather than a header item. Runer, do people often need to do that instead of using safeRAM and/or appvars? Do those temporary buffers exist as space taken up inside the programs even when they're not executing, in which case the buffers appear as modified data to Doors CS? Quigibo, you make some very good points there; I should talk to those Axiom writers about resetting their SMC areas if it wouldn't bloat their code too much.
