it's an internal routine as you can find out with
  print,routine_info(/system,/functions)

too bad it's not documented. Although IDL reserves the right to add
functions and procedures any time, I think it would be a better practice
to have a special naming for hidden (undocumented) routines. E.g.
__strtok__ would be a name that no one chooses out of lust.
Alternatively, I herewith formally demand to receive documentation on
this routine ;-)

Cheers,
Martin
