>I think the recent Acrobat 7, available for free, offers to fill out >such forms http://www.adobe.com/products/acrobat/acrrwhatsnew.html. >I haven't had to try this, so I have to guess whether this >advertisement is true. Every version of Reader has filled in forms. But... The pdf must be designed as a form for any program to be able to easily put the data in the right spot. Acrobat could have been used to create the fields for the data or it may just be a graphic of the original form. Reader can fill in the form and then you can print it with no saving of data in the pdf. Or Acrobat can be used and a form can be completed and the data saved in the pdf. Do note that Adobe Reader is the free program, and Acrobat is the full featured creator of pdfs.
