Hi Rolf:  it's not what's inside the lapplys that i was interested in 
which probably made my question more confusing. all i was trying to show 
was that,

in EXAMPLE 1, the name comes back at the top level of the result.

in EXAMPLE 2, i can use the name GGG inside the lapply functon to do 
whatever ( the whatever was just a stupid example which can be 
disregarded ).

my question is : is it possible to do both: be able to return the name 
at the top level but also mess with the name inside the lapply. i'm 
ccing the list again because it's quite clear that my question was ill 
posed. thanks for that enlightenment. I can't show my actual example 
because it's too complicated but essentially i want to be able to return 
GGG at the top level like EXAMPLE 1 does but also use GGG inside the 
lapply like EXAMPLE 2 does. Thanks for telling me that i'm confusing 
!!!!
