  • When is there ever a difference between \ and REFILL ?

    From none) (albert@21:1/5 to All on Thu Mar 2 14:40:21 2023
    Assume we have an word ?EOF that signifies the end of the input
    stream.
    Can we now define REFILL as
    : REFILL POSTPONE \ ?EOF 0= ;

    Note that this would be more general, because it works if the
    whole source file is slurped into memory.

    This wouldn't work for blocks where \ just discards the rest of the
    line (by advancing >IN) but does not refill the block buffer.
