Create a bunch of variables, then look in the mission file.  The index that FRED assigns them will be the index by which they can be accessed in variable-array-get/set.  (Note that FRED will alphabetize them before saving the mission.)

Could this information be added to variable-array-get/set's FRED help?  I guess since FRED lists the variables in alphabetic order in the editor it might be a "duh" moment for most people, but I never realized that's how they would be assigned indices too.

Nevermimd, answered my second question.

I can do this very easily.....

.....but only if I use my experimental SEXP-based collection classes build. I really should go back and get that code working properly!

It turns out that one of my assumptions is wrong: there isn't a way to access a variable array string value.   I'll have to make a version of variable-array-get that will do this.

This is now done.  The sexps copy-variable-from-index and copy-variable-between-indexes are now implemented, tested, and in SVN.
