chrmarker,
In Windows use the script editor to choose all tests then run the script.
In DOS under the diagnostics menu Page down/up through all the tests f10 will select/de-select all, then from the 1st menu press F5 to run all the tests. You can also save your selections to a PDO file which is like a windows script.
These and many more optins are explained in the manual included on your distribution CD.
