Steps:
- Start ArcPad in Design Mode.
- Click the Quick Fields tool on the main toolbar.
- Choose Add.
- Choose Layers.
- From the Layers drop-down list, choose the layer that needs an expression defined.
- From the Fields drop-down list, choose the field that needs an expression defined.
- Type a name for your expression.
- From the Filters drop-down list, choose your preferred function category. For example, choose System. From the Function drop-down list, choose a function from the category. In this example, the System category displays the User Name, Unique ID, Sequential ID, and Incremental ID functions.
When you choose a function, its name is displayed in the expression preview.
- Choose a separator (for example, _, /, \, or a space) or free text to add to your expression. As you add functions, separators, and text to your expression, the expression preview is updated.
