In-class Exercise
Creating Program Structures

---

In this exercise we'll be using the innate structure of LiveCode to rapidly create program structures similar to those we discussed in class.

1. Create a simple linear program structure.

• All handlers should be in a background group script or the scripts of grouped objects.
• All buttons and fields should be in a single group and that group should be on each card.
• Every card or page should display a Next and a Previous button. The Previous button should be automatically disabled on the first card, and the Next button should be automatically disabled on the last card.
• Each card should display a field telling which card you are currently on; i.e., "Card 2 of 5".

2. Create an open branching program structure.

• The program should include a main menu with at least three choices.
• There should be a separate background group for each branch.
• Each branch should be visually different from the other branches in some obvious way—background color, labels, or something else easy to spot.
• In each branch all handlers should be in the group script (or even higher in the hierarchy, as appropriate) or the scripts of grouped objects.
• In each branch all buttons and fields should be in a single group and that group should be on each card.
• Every card in the branches should display a Next and a Previous button. The Previous button should be automatically disabled on the first card of the branch, and the Next button should be automatically disabled on the last card of the branch.
• Each card or page should display a field telling which card in the branch you are currently on; i.e., "Card 2 of 5".
• In each branch there should be a button that takes the user back to the main menu. This button may be in each branch group, or it may be in a group, separate from the branch groups, that is placed on each card of the three branches.

3. Create a a Strict Branching structure by copying and modfying the Open Branching structure stack. This involves making the Return to Menu button only available on the last card of each branch.

When you are finished, drop your stacks into the Homework Drop folder on the server. Be sure to label them with your name. Due by next class period.
