Personally I'd have started at a different point to Kit.

You're working with local macros, as you clearly demonstrated with your
code so reading -man local- would be the obvious and intuitive place to
start.  Theres no obvious solution to your problem there, but there are
multiple references to -extended_fcn-, and the (possibly) intutitively
titled -tokenize- which could have been used as part of a solution to
your original problem.  The -extended_fcn- isn't obvious, but given its
prominence I'd have clicked through to read that which would have
mentioned the relevant macro for -word count string-.

In this instance there is no need for a "magic keyword", its just a case
of reading the documentation and related help pages for the functions
your using.

There is a definate art to searching though, you no doubt employ it when
searching the wider web/internet and the same approach can be applied
with a high degree of success to searching for a solution to a problem
with Stata (whether your searching Stata's help files, the archives or
the web at large).  A bit of trial and error, reading the results to see
if they are pretinent, and patience and perserverence  will usually get
you there (it might have got you to -renvars-).
