Hi Barry,

If you have IDL 8.1, you can now use multiple indices with List and
Hash. The first index gets the actual list (or hash) element, while
the remaining indices are used to index into the returned array. So in
your case, you could simply do:
print, splitnames[27,3]
This would take the 28th element of the list and extract the 4th
string. You can also use the usual array ranges, *, etc.

Regarding your particular problem, I am curious about what is wrong
with element 798. I'm worried there is a bug either in the strsplit
list code, or in the List::ToArray code, and I'd like to fix it. Can
you try the ::ToArray again, and when it halts with the error, print
out some info about element 798? For example:
HELP, splitnames[798]
PRINT, splitnames[798]

Thanks!
