I have no idea, but a C program could be written to parse and solve than in just
a few minutes.

Have you tried a chess database like Chess Assistant?  It can do all sorts of
marvels when it comes to looking for data and analyzing certain lines at your
discretion.  Considering all the effort you have expended, I am sure you would
be glad of such a purchase.  I don't have ChessBase, but I expect it has similar
abilities.

I fool around with SCID, but for serious work, Chess Assistant is miles ahead.
And it ought to be, considering that there is a large team of professionals that
do nothing all year except to work on it.
