ZIP files are a common compressed format to distribute files on the Internet.
To use a ZIP file, you will need to uncompress it. There are many free programs that can uncompress ZIP files downloaded from the Internet. We recommend Winzip for Windows computers and StuffIt for Macintosh computers. When I run your PalmOS software, I get a CASL runtime error. This file is included in our downloaded ZIP file.
