MS-DOS Batch File for Viewing Large Document Scans
The following is a "simple-little-batch" file illustrating document viewing from the DOS prompt, that is available on our BBS in the ZIPfile, DOCBAT.ZIP. In addition, the sample images are also available, as well as several other examples that may prove useful. Please call for an account on our private BBS. Essentially, the same concepts used in VIEWDOC.BAT, are used with Clipper and SunShow function libraries.
