Sub Systems, Inc.

Sub Systems offer high quality, robust and feature-packed software controls. In the late eighties, we released our first product, the text editing kit for DOS. TE Developer’s Kit was released in 1990 for the Windows platform and was the first text edit control available for Windows. We also released the first spell checker library for the Windows environment in 1991. HTML add-on was released in 1995 before the web exploded into popularity.
