Speed testing on DOSBox: for a file with 103,000 characters I did ci /{X}/x/ where{X} is the any-character symbol. Time in DOSBox--pretty much independent of CPU cycles or Frameskip: 20 - 22 seconds. Time in regular Win98--1 second. This means DOSBox is too slow for my Xy-use. Harry Binswanger hb@xxxxxxxx
