Rick, As I recall, JustText (?) is the only popular program that uses the AFM files. All other major programs can pick up the font's width and kerning info from the screen font file. <BW> P.S. You sure sent me scrambling this week, looking for Finder Sounds here on CIS. Have you heard if they've been uploaded here, yet? (I already have a copy from a friend that got them from "another" service, but I'd love to be able to point out the location to others that are using CIS and System 6.04.)

The AFM files are more for reference than anything else. The Mac doesn't actually *use* the AFM files since all the font metrics are contained within the font itself. What AFM files are useful for is helping other programs "load" font widths. For instance, Magnatype uses AFMS to load font widths and kern information for its PostScript module. We have one client who wrote their own publishing software and they too use AFMs to load font widths and kerns. The AFM files are also of great use to PS programmers. For instance, if you want to create a new accented character, you have to refer to the AFMs to figure out precisely where to place the accent. In short, yes, you're right, the info is all contained within the font, but the AFMs are a handy ASCII version of the info which can be accessed a lot easier than trying to pick the font apart. Ventura Publisher, BTW, uses an abbreviated form of the AFM files to generate its width and kern tables. The only programs that I know of that actually *use* AFM files are PC-based.
