about position.lrn


<snip>

Crafty now has a permanent hash table that is kept from game
to  game. A position gets into this hash table when a search
value is significantly lower than the last search value. The
permanent hash table can hold up to 65536 positions. Once it
fills up, the positions are replaced on a FIFO basis, always
keeping the most recent 64K entries. Each time Crafty starts
a search, the positions  and  scores  from  this  table  are
stuffed into the normal transposition table, and used during
the search just like any other table entry.

from the crafty ftp site (under crafty.doc)

so it means that the position.lrn file doesnt get larger than 64000 entries. ;(.
and its a default setting.
why is it done ? I mean why is it restricted to only 64k?
Is it possible to make it infinite? ( no size restriction)
Is there a certain code that needs to be changed to overcome this problem,
I would graetly appreciate your help. :)
thanks
Pavel
