It might be possible to change the built-in close routine into a function that returns -1 when it successfully closes a file, but we'd have to think that through a bit more for ramifications to existing code.
But -1 is an error flag. A file being closed isn't an error, i have at least 100 lbs of closed files. For now, i set writefile to zero to detect if i ever opened the writefile in question. So 4 = i'm writing, -1 = there's some error, 0 = better open it first. Come to think of it, maybe some other (nested) flag(s) which also show(s) how it was open, like "ab", or "w", and when, and maybe who.
