TVRD() does work on win2k (idl5.6)

That message results when you call it as a procedure, and it cannot
find the procedure definition.
If you called a nonexistent function, IDL will think it is an array,
and give you a syntax error (unless you changed the compiler settings).
(or it gives you a "variable is undefined" if you call it with a parameter).

If you start up IDL, you should be able to type
IDL> help,tvrd()
at the command line and see it work.
