How do I add a password to a document?

[mrs_overall]

I have a lengthy document in MS Works word processing. Is there any way I can add a password just to this document to keep it away from prying eyes?

Go to 'File, ' then 'save as' click on 'tools' (on the right hand side of the box) and you will have a drop down menu, chose 'security options.' You'll be prompted from there.

(If you have already saved the document then you don't need to do 'save as')

I've just tried that. I clicked on 'file' and then 'save as' but there was no tools option. I'm working with a new PC that doesn't have MS Word on it, only MS Works. (I knew how to add a password on my old PC in MS Word.) Infernal machines! Thanks anyway China Doll.
