On October 26th, 2018 I purchased the software assets of Full Moon Software.
Full Moon Software used to be known as Crescent Software. They produced a line
of excellent development libraries for MS-DOS. The supported environments were
QuickBASIC 4.x, Microsoft Professional Development System v7.x, and Visual
Basic for DOS.

The idea behind obtaining these products was to release them to the public
domain to ensure that people could still access these things in the future.
While most developers will have no use for these products in a modern
develoment environment, they still have value as an example of "how it was
done" back in the heyday of x86 DOS development.

The software in this repository hasn't been modified from how I received it
from Ethan Winer, the original author. While all the source files carry some
kind of Copyright notice, the software is now in the public domain.

The contents of the installation floppies will be uploaded to the Internet
Archive soon and when the manuals are scanned, they'll be uploaded there
as well. I'll update this page with links to the manual scans when
they are available.

The home page for Full Moon Software can be found here.

About Crescent Software:
After 20 years as a professional recording engineer and musician, Ethan
Winer founded Crescent Software in 1986, quickly building it to become the
leading provider of add-on products for use with Microsoft compiled BASIC
for DOS. During that time Ethan wrote numerous articles about DOS BASIC and
assembly language for all of the major programming magazines, and also
served as a contributing editor for PC Magazine. Ethan also received
Microsoft's MVP award every year since 1996 for his assistance in the
Microsoft BASIC programming newsgroups. In 1992 Ethan sold Crescent to his
partner Don Malin, and retired in order to pursue his musical interests.
