Do you know of a way to get Alibaba to generate a log file?  The way I got that
was to copy & paste from the Dos box, which wasn't too strenuous at the speed it
was going.  But I might be overlooking something obvious for making a log.

It's a cool little program.  If you can live without castleling you could play a
game against Alibaba no problem.  I'll have to get around to it soon, maybe keep
track of the game on Winboard.
