Dear Alexander,
Fluka could read more than 9999 bodies, but there is a bug in a I/O
statement..thanks for pointing this out.
The bug fix will be released with the next respin.
 In the meantime, the solution to your problem is to use the name based
geometry input (COMBNAME in the GEOBEGIN sdum, for details refer to the
manual), that is also much more flexible and easier to
write/read/maintain.
Regards
Paola
