Jodi and all--- If the very low intensity of physical processing either can't identify record series, or at least can't disentangle them meaningfully, why not simply code every resulting <c0x> as @LEVEL=file? Then the coding is intellectually sound, and it reflects the circumstance that no useful hierarchy presents itself in their arrangement.
