Re: Translate String of Variable Name into Variable Value

[spam@...]

Thanks. The "const" is part of a class definition. I left
that bit out for simplification, but the distinction may be
important. Can I still access the value through _G[] ?

there are no "consts" in Lua, but you can emulate constants
with proxy
tables. and you can do something like:

function CompareVar (varname, value)
  return _G[varname] == value;
end;

this is identical to simple "varname == value" construction.
