Defining a New Environment Variable on the Custom Build Tab

Choose Settings from the Platform menu to display the Platform Settings dialog box, and then select a feature in the FeatureView window.
Choose the Custom Build tab, and then choose the applicable configuration in the Settings For window.
Choose either Feature Build or Make Image in the Build Step box.
Choose the Environment Variables For This Build Step window to switch to this window, and then choose New.
In the New Build Setting dialog box, type the name of the environment variable in the Variable box, and then type the value in the Value box.

Certain environment variables, for example ones set by WINCE.BAT, can be used to specify the value.
