that reference repeats the HTML syntax for a jump to a

location in the same page. Figure 6 displays the result.

Figure 6 shows the simulated output for this first list.

Immediately, the constraints of the small screen become

apparent. The wordiness of the descriptions is too much

for this device to display well. In Figure 7 the descrip-

tive text has is shorter and the list fits comfortably on the

screen.

The user selects a list option by means of the arrow

keys or by pressing the number corresponding to the cho-

sen list entry. In Figure 7, the Museums entry is chosen.

Pressing the button under the check mark will make the

selection. To continue the application development, the

additional cards are added to the deck. The empty cards

are shown below:

The initial display looks no different, but now there is

a card corresponding to each choice. The cards are cur-

rently empty, ready to be filled in with relevant informa-

tion for this application.
