I recall, many years ago, having problems with that. I was trying to write a
File IO library that would be portable to Unix and VMS, and needed files to
be of arbitraty length. RMS only supported files whose length was divisible
by 4 (or perhaps 2), so that required using the ACP's QIO interface. Not
fun.
