Not only (eof). Any reading beyond end of file causes this state to be remembered in the character-look-ahead buffer of the I/O system, so that further reading returns NIL. But I think this was not the problem of the initial poster, where the low-level read() did not return. The look-ahead happens on a higher level. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
