DIS to CAL Conversion: FAQ

The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
