oh, great, another portability. Well, after you pointed this out
i realized it does vary a lot from machine to machine. I wrote 
a quicky to test it on SunOS 4.0 and it appears that the stream
gets closed for you. 
   I don't have the intestinal fortitude to test this out on our varied
machines. I *really* don't want to know ...
   So, Rule Number One: the definition and side-effects of eof 
are about as well-defined in stdio as they are in Pascal. arg.
