BASIC Web Utility • This is a set of BB programs that facilitate active HTML web pages by using cgi. • The idea is that the BWU programs act as a “blackbox” between your data and the webserver. • This makes web presentation of BB data quite fast and easily added to a legacy installation. • Quick connect and release so it uses fewer licenses.

Mobile Computing – Windows Scripting Host • This is quite similar to the BWU except that it uses WSH in place of the BWU programs. • WSH requires a Microsoft webserver. • The BB code can be quite simple since it prints to the browser display. • Uses ASP via a browser.
