Thanks all. Bruce's reply was especially helpful. I understand my various imperfect options now.
With regard to R.S.'s observation: ain't it the truth! Does anyone have the impression that making* a simple question like "how big is this file?" so darned difficult somehow improves the value or the positive attributes (RAS, etc.) of this platform? *Yes, MAKING. Some of the problems are inevitable due to the age of the platform and the philosophy of upward compatibility (small field sizes that have now been outgrown in some kludgey way) but IBM's placing a prohibitive price on fundamental (if PC-DOS can do it, it's fundamental) documentation is totally incomprehensible.
