The %DLC% environment variable is not set at the system level and should not be changed. After installing OpenEdge, however, you can set environment variables to suit your own preferences. You can use Proenv to set the %DLC% environment variable to the directory where OpenEdge is installed.
Caution: Although editing environment variables is an option, this procedure is not recommended if more than one version of an OpenEdge product exists on the same system.
For more information on environment variables, see the information on maintaining user environments in OpenEdge Deployment: Managing ABL Applications, or see your specific product documentation.
