1. What is a linear stack and why would one choose to design a linear stack?
[In a linear stack, the cards are arranged so that the cards are viewed in a given order. The design is useful for presenting information in a step-wise fashion, such as images of the proper order of assembling a musical instrument. The student may view each card at his own pace, but the order of cards is set. Timing functions can be useful for presenting images coordinated with a musical recording.]
2. How does one add timing functions to a linear stack?
[For any object, use the automatic timer option in the Actions dialog.]
Use MOVENEXT, and WAIT to create a button that presents each card for a specified time. Use a REPEAT loop and IF BUTTONP to set up a WAIT that can be interrupted by a mouse
