Eric Gans French Dep't UCLA Los Angeles, CA 90024 DMAP.COM (v.1) creates a display from the disk allocation vector that shows which blocks are/are not in use. Rather than the traditional bitmap, which is no more readable than the vector itself, the display contains the block numbers, as well as a total of blocks in use. (If you can't see the used blocks, you don't have K-10 graphics! The video attributes addresses are: inverse video on: 3CD-3CFH off: 3D1-3D3H.) [dmap for current drive, dmap b (or c...) for another.]
