"//" and "#" both get striped out on a resave from document to pallet. I never heard of "*" being used before, but my bet is that it gets striped out as well. Jagger's "material comment" does not get striped out. A "valueParm", and probably any other channel type, can be used to preface a permanent comment, if it is followed by matching braces: valueParm My Comment 13-12-02 { } But poser will add a lot of standard channel code when you resave to a pallet, and the channel should be put in the normal place for a channel, not in the middle of another channel.
