The directory $SAS_DIR/config/ftools should be placed at the start of your SAS_PATH:
setenv SAS_PATH $SAS_DIR/config/ftools:$SAS_DIR
This causes the supported FTOOLS to appear on an `ftools' sub-menu of the `Task' menu.
The SAS GUI should not be placed in the background (with `&') when it is started. It is then possible to respond to prompts from tools, by typing in the terminal window from which the SAS GUI was started.
