About ProDOSifier ProDOSifier is an AppleScript program to help with ProDOS files on a Macintosh. It can set file types, batch process, sort through file extensions, save directory listings, and combine text files, all in the same program, and accepts various formats of input. Instructions are included. Hint: If you have OSAMenu installed, you can create an alias for ProDOSifier and put it in your Finder Scripts folder. Make sure to select the Use Finder for Applets and Droplets option before you use ProDOSifier from the menu (otherwise the computer will crash). Changing the name of the alias to "ProDOSify...\Y" (without quotes) gives the menu item a nice "official Finder command" look.
