I see your reasoning, but I do not understand why eof doesn't return always. The eof is not a 'wait for eof', but a test. If we're _not_ at the end of the file, the program should return with false, at least how I understand it. program test1; var v: integer; begin if not eof then begin write('Wait for input '); readln(v); end; end. the eof call here, makes the program invert it's output, as the eof waits for the buffer to be filled (so the number is already on the screen) then outputs the 'Wait for input' text. It doesn't feel right... I guess the eof call is superfluous here, but it wouldn't be so illogical if the input channel is redirected (eg. from a file). Thanks for your input (pun intended ;-) John _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
