Here's how to transfer Apple II VisiCalc files to an MS-DOS format:
1. Save the Apple II VisiCalc file to disk in the DIF format.
2. Transfer the file, via terminal software, to the MS-DOS system.
3. Save the file.
The file can now be read into any of the MS-DOS spreadsheet applications
that support a DIF format -- Lotus 1-2-3, for example.
