## Using Expressions in a Part Program

The PC-DMIS Edit window allows expressions in most of its editable fields. Editable fields are usually those fields highlighted in yellow when you press TAB inside the Edit window while in Command mode. Fields that change the type of the feature do not allow expressions.

Example: The box of an auto feature which specifies the type of the auto feature; i.e. Surface point, Auto Circle, Auto Round Slot, etc.; does not allow expressions.

The subtopics under this topic offer a complete reference to available expressions.
