Thanks for the reply.  Sadly, I am not a programmer and do not have C or
the tbgen source code, so cannot easily implement your solution.  Time
to start again.

It seems from the time it took you to generate KRRKR that you have
something other than a slow PC - unless I missed a trick.  (I simply
downloaded the zipped version of tbgen.exe at chess.onenet and set it
going, without anything on the command line other than directory paths
for the various files.).
