	An ARexx script can receive initial settings through icon tool types. The tool types are stored in an icon file which can be identified from the .info extension.		An ARexx script can receive initial settings through icon [[UI_Style_Guide_Workbench#Tool_Types\|tool types]]. The tool types are stored in an icon file which can be identified from the .info extension.

	You can add tool types for your ARexx script through Worbench's icon information window: in the Workbench, select the script's icon and then select '''Information...''' from the Workbench's '''Icons''' menu. This will open the icon information window. Click the window's '''Icon''' tab and you can see the '''Tool types''' editing gadget. Enter your tool types there and click '''Save'''.
