multiple response set

[F. Thomas]

Hi,
I found the MRSETS command which allows to analyse multiple reponse 
questions;
But the MULT RESPONSE command has not yet been implemented, according to 
the manual.
So how to analyse mult response questions ? What can you do with MRSETS 
when you have no Mult response frequencies or tables ?
Or do I miss something ?

And what does the cryptic sentence mean (manual p.113)
Otherwise, multiple response sets are currently used only by third party 
software.
Could you please be more specific ? Which third party software do you mean ?
