/* Now we get serious and add a data structure and entry fields to */
/* collect information from the user. */
/* We add quite a bit of code but it is really quite straightforward. The */
/* bulk of the code is repetive, gathering data for similar data fields. */
/* Notice that we add a function to display a customer. We simply pass */
/* a pointer to desired customer and a pointer to the window in which to */
/* display the customer's information. */
/* We use the function wn_gets_ll (low-level) for maximum flexibility. */
/* Refer to the function reference for details of this function. Once the */
/* basic parameters are understood, it is quite easy to use. */
