: Ahem.  Consider (in UNIX shell notation):
:       filter <infile >outfile

: There really is no way to do this right in the application code;
: it has to be dealt with in the run-time environment.

Please recall that he wanted a fix for his Macintosh, where there
is no such thing as a command line, much less redirection.
(Actually, I hear that there is a kludge in Lightspeed C that
lets the user type in part of a command line at program start;
but according to a guy who is working with that compiler,
getchar() echoes when this kludge is used, so I suppose that the
guy with the problem isn't using this kludge.)

Of course, you really should have got me for this; I wrote:

: #define getchar()       (putchar(getchar()))

And I should have written:

: #define getchar()       (putchar(getc(stdin)))

I do agree that this would be a brain-damaged thing to do on
almost any other system.  And, I agree, the run-time environment
should deal with this; that was the first thing I said in the
message that you responded to:
