If we're _not_ at the end of the file, the program should return with false, at least how I understand it. It is not possible to know whether you are at the end of a file or device without (attempting to) read from it (unless you previously hit the eof marker).

This sample program doesn't return till enter is pressed.
That's correct and reasonable. You are terminating your program after an EOL
(ENTER), If
you send it an EOF ^d it also responds reasonably.
$ ./testeof
^d entered at kybd
EOF found

[fpc-pascal] eof strangeness
Hi all.
While modifying some older programs, I found a strange effect with eof
(input). When calling eof(input), the program needs an enter key to
continue. I just downloaded 2.0.2, with the same result.
The definition of eof (according to the FPC docs) is that it immediately
returns... which is what I need. Can anyone suggest a solution for this?
program testeof;
begin
if eof then
writeln('EOF found')
else
writeln('No EOF found');
end.
This sample program doesn't return till enter is pressed.
TIA,
John
