Understand® is an IDE built from the ground up to help you fully comprehend your source code. Analyze it, measure it, visualize it, maintain it - Understand it.
If your code is safety or mission critical or has grown larger than one person can handle, you owe it to yourself to try out Understand. Understand will help you discover exactly what your code is doing and why, and you will soon be wondering how you lived without it. Join the 20,000 other engineers that already Understand their code and try a fully functional trial now, or learn more.
I have been a long time user (since 2001) of the Understand tools, starting with Understand for Ada and Understand for C++. I use the Understand package as an IDE for the Ada. It helps eliminate syntactical errors and many other problems before submitting the code to the actual compiler on another computer.
On an average week, I use the Understand tool about 30-35 hours per week.
