If this environment variable is set, it should contain a list of directories in the same format as used for the system's PATH environment variable. These directories are searched (before the directories that QMTest searches by default) when looking for extension classes such as test classes and database classes.

If this environment variable is set, its value is used as the location of the test database, unless the --tdb (-D) option is used. If this environment variable is not set and the --tdb option is not used, the current directory is used as the test database.
