Step 3 - Clear All Previous Modifier Values

Since the commands are initialised out of context, the modifiers for the commands are not set up in the normal way. Modal values are not loaded, and neither are lists that are initialised dynamically by the command. To aid clarity in the PCI, all modifiers for all commands used in an operation will be cleared using %CLEARMODS:

%CLEARMODS=[cmdMillTool]
%CLEARMODS=[cmdRapidMove]
%CLEARMODS=[cmdFaceMill]
%CLEARMODS=[cmdHome]
