This bug has existed since 3.0.  I (and others) complained to DEC and they
said that it would be fixed in 3.1.  They sent me a patch for getch() that
works for arrow keys (but not for other stuff like PrevScreen, NextScreen,
Select, etc.) so I can't understand why they didn't include it in 3.1.

Anyone that wants a copy of the patch can e-mail me.  *Maybe* it will be
fixed in 4.0.

I'm not sure what (if any) connection exists between the problem with getch()
and fopen().  From the small example program you included, it looks like
fopen() would never get called because it would never break out of the
for(;;) loop.
