RE: %OFFSET

 >> If I have a datastructure, full of variable length fields, how do I
determine the offset to a particular field?

The varying length fields always occupy the same amount of storage - i.e.
the maximum length + 2.  They are only _treated_ as being variable in length
when used.  So to calculate the offset is no different than for a fixed
length field - Addr(VarFieldn) - %Addr(DS).  For the actual data content (as
opposed to the length) you need to add 2 to that.

I'm fascinated as to why you want to know the offset.
