Yes, I'm quite sure that I have enough information to work with.  
Thanks again to everyone who responded!

No (but there are other recordtype prefixes I did not mention).

No, the appearance of data in any given file will always be self-
consistent (that is, all data has the same pattern within any single 
file).

No, except that I think all characters output as headers will be only 
uppercase, compared to typical "pure textual data".  (In that case, 
perhaps a regular expression could help distinguish them.)
