I just finished testing an XB version of one of my simpler TB programs which Skywise was kind enough to convert for me.

The programs read files for moon declination, perigee and syzygy or 2012-2014, then compare that with mag 7+ quakes, looking for matches.

There are a few, just as chance allows.

TB takes 0.875 seconds to do it but only 0.6 seconds under the DOS version of TB while XB takes only 0.453 seconds to do it.

That isn't enough difference to suffer the vagaries of XB except for one thing; XB works under Linux as well as Windows.

One surprising thing (to me, anyway) was that reading a line and decoding substrings into variables was twice as fast as reading the variables directly from a .CSV file.
