Here, the ";" unambiguously indicates the end of a command line, which just happens to be empty. I'm not completely sure it's a bug. Compare, for example, the behaviour of "for f in ; do; done". It's quite useful that this simply does nothing. (Whether it's valid according to the various standards is another matter.) > (Perhaps the patch should set tok = LEXERR only when tok == ENDINPUT ? > I couldn't decide.) It looks safer the way it is. -- Peter Stephenson Software Engineer CSR Ltd., Science Park, Milton Road, Cambridge, CB4 0WH, UK Tel: +44 (0)1223 692070 ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
