That's inherent in the nature of printing terminals: 'X', BS, '_' worked fine on all such terminals to produce an underlined X. Later it was found to be better to use '_', BS, 'X', which looked the same on actual TTYs or equivalents (LA34/36) and was greatly superior on video terminals. -- John Cowan http://www.ccil.org/~cowan cowan at ccil.org Any sufficiently-complicated C or Fortran program contains an ad-hoc, informally-specified bug-ridden slow implementation of half of Common Lisp. --Greenspun's Tenth Rule of Programming (rules 1-9 are unknown)
