load

Loads a chunk using function func to get its pieces. Each call to func must return a string that concatenates with previous results. A return of an empty string, nil, or no value signals the end of the chunk. If there are no errors, returns the compiled chunk as a function; otherwise, returns nil plus the error message. The environment of the returned function is the global environment. chunkname is used as the chunk name for error messages and debug information. When absent, it defaults to "=(load)".
