By default, the OpenEdge installation program tailors all the necessary OpenEdge and Java environment variables to where they are installed. After installing OpenEdge, you can use the command-line utility (Proenv) to access these environment variables.
Caution: Although editing environment variables is an option, this procedure is not recommended if Progress Version 8.3 and Version 9 (or WebSpeed Version 2.x and Version 3.x) products exist on the same system.
For more information on environment variables for OpenEdge, see the information on maintaining user environments in OpenEdge Deployment: Managing ABL Applications or refer to your specific product documentation.
