Re: $fopen/$fclose

Jonathan -
I hadn't noticed the omission of MODE for opening a file.
The AMS LRM is somewhat vague about what mode is used:
you get an error if the file can't be opened for writing,
so I guess that means the mode in AMS is "w" (not "a") --
but this should be noted explicitly.

I had noticed the omission of $fwrite, etc. while I was
doing LRM 2.2, but thought that these would get added to
LRM 2.3 when aligning with 1364-2001.  (And this wasn't
a compact modeling issue, so it wasn't mine to fix.)
