What is the reason behind using 'T' for status, is not 'S' a good alternative as that letter is not used?

What about WALL, should that exist? Can I add that as 12 (or perhaps even 0)?

I honestly don't know why I used "T", as you say "S" would also work...maybe I was considering another type that started with 'S" and never got around it, but I don't remember.

Edited: I remember now: I reserved "S" for a STACK backup, either the "real" one or the Shadow Stack in the WARP_Core module (which really is buffer#7 but that's another story)
I also toyed with a Polynomial File but after some reflection I decided to use Data Files for them, not different enough to warrant a separate kind.

WALL files in X-Mem? I'm not aware of any function creating that kind but if you're working on one by all means using 12 or 13 for its type will be compatible.

I'd stay away from "0" as a valid file type... not sure that'll break code somewhere?
