1.17. Programming Languages and History of @RISK

Applies to:
All products, releases 6.x–7.x

I've always wondered -- what language are your products written in? What programming language do you use? When was @RISK first released?

Current versions use a mix of C++, Visual Basic 6, Visual Basic for Applications, Visual Basic .NET, and C#.

The first version of @RISK for Lotus 1-2-3 was released at the beginning of October 1987. Its predecessor product, PRISM for DOS, was released in April of 1984. Earlier versions of PRISM for Apple II were in use starting in 1982, before Palisade was organized as a company in 1984.

@RISK for Excel first appeared some time before July 1993—the earliest user manual in our archives has that date for @RISK 1.1.1—and @RISK for Project in 1994. In July 2012, @RISK 6.0 integrated support for Excel and Project.
