You are a developer in the IT department of a municipal utility. You have been tasked with integrating two applications that are already in production.
The first application is a customer management system. Its main form is the Customers form, in which utility clerks enter and update customer information.
The second application is a GIS application. One of its forms, the Address form, enables clerks to enter an address, click a button, and have the address verified and property formatted according to postal standards. You need to add a button to the Customers form that will pass the customer address to the Address form and receive the properly formatted address back. A variable of the user-defined type Addr_Typ will contain the address information to be passed back and forth between the two users.
