To create a logical disk: create file.dsk/alloc:494. (rx01 size, RX02=988, rx50=800) mount ld0 file.dsk dk (mount as LD0, assign ld0 dk) init/bad/noq dk: (impose a directory structure) now proceed to use ld0 as you would any other device... If you already have a disk image with stuff in it.. mount ld0 image.dsk dk (mount existing file as ld0, assign ld0 dk) dir (get a directory) Again, just use it as you would any other disk volume.
