Dat and obj question.

When I do a conversion from standard obj file to import to a dat
9/1 13/2 12/3 converts to hex = 8 12 11 0 1 2
Haveing not looked at all dats, is this standard game wide?
The fact that it drops a full point?

Then the other 2 conversions.
Standard game wide?
Or do I need to dig a bit deeper?

Don't want how to do it, just a pointer.
I learn better that way.
