if your doing something like this :

gemhead
|
repeat 20
|
gemlist_info
|
translate
|
rotate
|
scale
|
sphere

then, the gemlist_info will (should) output data before each sphere.
you can use [print] to check that the data are available...

gemlist_info work as expected (i think) : it just output information 
about the gemlist it receive....

if you want to track the position of the 1st, 2nd and last sphere in 
your chain, you can do something like this :

gemhead
|
t a a a a a
   | | | | |
   | | | | gemlist_info : 1st sphere informations
   | | | |
   | | | s repeat_primitive
   | | |
   | | gemlist_info : 2nd sphere informations
   | |
   | repeat 18
   | |
   | s repeat_primitive
   |
   gemlist_info : last sphere informations
   |
   s repeat_primitive


r repeat_primitive
|
sphere
|
translate
|
rotate
|
scale
