Thanks for the reply

I tried to check with the style numbers in the mdf file, but I guess that there is an extra conversion table as they don't really look alike.

At least when saved in the user tab the s900 seems to generate each time a new number in an incremental way starting at hex 20:
F0 43 73 01 51 05 00 03 04 01 00 00 20 F7

Note the 01 after 03 04 .., I guess that indicates a user style.
