Start SCAS, and the window appears as shown in the figure below. First let's learn about the function of each window.

In order to use graphics files in SCAS, they must first be registered with SCAS as an image.
Let's register all the images we will use.
Register SP01, SP02, earth01, earth02, earth03, and earth 04.

Now, we will set the background color. To match the theme of the content we are now creating (space), select black.

To work in the Graphics Track Window, we must create a block.

A block is a container for images or text.
Putting all related images and text in a block makes it very easy to move or delete items.

To open the Block Edit window, double click the block.
Edit the content of this block using the Block Edit window.

1. Let's enter the greeting "Hello World!"

2. Play with the emulator
Use the emulator to play the file and check your work.
After a few seconds, the phrase "Hello World!" should appear in the Emulator window.

3. Add Text Color Blink
Set the color blink. Open the Text Event dialog box.

Press play on the Emulator and confirm that the Color Blink is active.
