Right-oh dodger! I was thinking of mentioning some of that, but thought I'd wait and see how long until you posted the .rsr text :) They are all null terminated strings, but actually have the leading tab character's. Not sure it always requires the correct number of tabs, but I've heard that there are some occassions where it does, so seeing it laid out the way you did perhaps explains it. The syntax is very helpful - I was trying to see if I could sluff in some uv coordinate changes along with morph deltas, so by looking at the syntax you can see it will only read the first three floats. To bad, so sad... Back to the drawing board.
