I'll take your word for it, but I can't actually find anything in the RM95
specifically to that effect. (Is that what you mean by "they don't have
to"?.)

One point I'd like to throw in 'from left field', as they say, seeing
certain comments in other posts in this thread: I don't see any sensible way
in which one file object (in the RM95 A.7 sense) can be used simultaneously
for input and output; what is possible (and sensible) is for two file
objects to provide input and output (respectively) for the same external
file (e.g. device). Typically, Standard_Input and Standard_Output work this
way.
