Ranger is a diagnostic tool for Amiga OS4 made by Steven Solie. Ranger will automatically update the list of processes and DOS devices as they are added and removed. Changes in this version: DOS/Devices/Block now displays the correct block size in bytes. Added “Open File Handles”. BIOS version information is disabled if no biosversion.resource is present.
