4.3 Loop Control System - Changing the Loop Sequence

In this exercise, you will change the loop sequence with the LB and LS commands.

1. Change the loop bounds to be from frames 1 through 6.

Type: LB 1 6

Notice that the loop bounds on the status line changes to 1-6 and frame 1 is displayed.

2. Start and stop the loop.

Press: Alt L
Press: Alt L

3. Define a loop with random sequencing.

Type: LS 1 3 2

The primary loop is frames 1, 3 and 2, and the opposite loop is frames 4, 6, and 5. Notice that the status display at the bottom of the text and command window changes to indicate that the loop is random.

```  IMA GRA Bounds Switches                          Date        Time   T
1   1 random                              23 Oct 2000297 19:02:35 0
```

4. Set the opposite loop to display a random sequence.

Type: LS O 6 5 4

5. Check the current loop settings.

Type: LS

The primary loop is frames 1, 3, and 2, and the opposite loop is frames 6, 5, and 4. The dwell rate for both loops is nine units for the first frame and six units for the remaining frames.

6. Loop the primary sequence, the loop set in step 3.

Press: Alt L

Notice the frames loop from frame 1 to 3 to 2.

7. Toggle to the opposite loop sequence.

Press: Alt O

8. Toggle back to the primary loop sequence.

Press: Alt O

9. Stop looping.

Press: Alt L
