Thanks - it apears that like .sgf, chequers are considered off if they
aren't somewhere else

OK - most of a .txt file makes sense to me (I think):

The files are a single line with fields separated by
semicolons. Fields are numeric, except for player names.

Field no    meaning
0           length of match (0 in money games)
1           1 if Jacoby enabled, 0 in match play or disabled
2           Don't know, all samples had 0. Maybe it's Nack gammon or
            some other variant?
3           Don't know. It was one in all money game samples, 0 in
            match samples
4           Player on roll 0 = 1st player
5,6         Player names
7           1 = Crawford game
8,9         Scores for player 0, 1
10          Cube value
11          Cube owner 1 = player on roll, 2 = centred, -1 opponent
12          Chequers on bar for player on roll
13..36      Points 1..24 from player on roll's point of view
            0 = empty, positive nos. for player on roll, negative 
            for opponent
37          Chequers on bar for opponent
38.39       Current roll (0,0 if not rolled)

The attached perl script takes a snowie .txt file on stdin and writes
a .sgf file to stdout (Unix users could chmod it and run it as a
command, under Windows I assume you need to do 

C:> perl < snowie.txt > gnubg.sgf

I tried all the positions Micheal sent me and they all appear to be
correct in the output (the ones from Gammonline postings match the
posted ones),
