An 8088 takes much more than 4 cycles to load a register on average. A
6809
takes between 2 and 8, but they are *real* numbers, not the pie-in-the-sky
numbers Intel used in their docs. A 6809 also has 16-bit registers, and an
8
* 8 MUL. A call ([L]BSR) takes 7 or 9 cycles, and a ret (RTS) takes 5.

Me too, since this is perfectly legal *if* IBN is a true constant. The
*only* answer I can think of is that IBN is not in scope when you define
your TPlayer - it either hasn't been defined yet, or the unit it's
declared
in is not in your "uses" statement.
One thing's for sure, the error has nothing (directly) to do with it being
used as part of an objects definition.
