Cheers David. Just what I needed--saves me a lot of code.

All globals, including functions, are (usually) stored in a special
table called _G. So all you need to do is:

function callfunction(n, ...)
  local name = AtcActions(n)
  local f = _G[name]
  return f(...)
end

e.g.:
print(callfunction("2", "word"))
