hmm... it seems to me that 'result' is the array you are looking for:
it has the elements in the order you want, and they have the indices
numbered from zero (i.e. there are no empty elements). I don't see why
you would want the dimensions of mylist or result to be the same as
namelist. mylist is given to you, and has its own size - the code will
work whatever its size; 'result' is calculated and has its own
'dynamically allocated' size.

If you're sure you want an output with blanks - although I can't see
how you would use it - try tacking this on the end:

result2=namelist
result2[where(total(s,2) eq 0)]=''

IDL> print,'#'+result2+'#'
## #Groggy# ## ## #Emmy# ## #Jockey# ## #Itchy# #Fluffy#

So you have namelist with the unneeded elements set to empty.

If I still haven't got it, perhaps you could write what you would
expect the output to look like for a couple of cases.

regards,
Greg
