- Graphics Module Tutorial
-
-
- This tutorial will guide you through the creation of a very simple animated
- drawing. Although you can probably get through this short tutorial without it,
- I'm going to assume that you have read the manual. The manual is located in
- the manual.doc file.
-
- Load the program by entering the command GO. Now press the ENTER key twice.
- If you will be using a Microsoft (tm) mouse then press y. If not press n.
- You should now be in MAIN GRAPHICS MENU. Press the number 1 key to get into
- the GRAPH menu. Finally, press 1 again to get into the DRAW menu.
-
- Note: It's actually much easier to draw using the mouse. When using the mouse
- remember that the left button can be used for "yes" or in place of the ENTER
- key. The right button can be use for "no" or in place of the ESC key. This
- tutorial was written assuming you don't have a mouse. If you have a mouse and
- have installed the mouse driver, always look at the top of the screen for
- button clicking instructions.
-
- Now it's time to draw something. These are the steps:
-
- 1. DRAW A LINE
- a. Choose the LINE option using the keyboard or the mouse as explained
- in the manual.
- b. Choose the color BLUE. Press 1 on the keyboard.
- c. Move the cursor to 150,85 using the arrow keys or the mouse then
- press ENTER. This selects the beginning of the line.
- d. Move the cursor to 180,85 then press ENTER to select the end point of
- the line. The line is now drawn and you're back in the DRAW menu.
-
- 2. PLACE AN ANIMATE MARK
- a. Press the number 5 key to get back to the GRAPH menu.
- b. Press the > key to see the additional options.
- c. Press the number 6 key to choose the ANIMATE MARK option.
- This stores the existing drawing as an animate screen.
- d. Press the < key to see the lower GRAPH options.
- e. Press the 1 key to choose the DRAW menu again.
-
- 3. HIDE THE EXISTING LINE
- Use the previous step #1 to draw a line over the existing line but this
- time choose the color NONE. This will erase the existing line without
- deleting it.
-
- 4. DRAW A BOX
- a. Choose the BOX option by pressing 2.
- b. Choose the color WHITE by pressing 3.

- corner of the box. The box is now drawn.
-
- 5. PLACE ANOTHER ANIMATE MARK
- Repeat step #2 to store this drawing as an animation screen.
-
- 6. HIDE THE EXISTING BOX
- To hide the box we could draw over it in the color NONE but I want to
- show you another technique. This technique is faster if you have a lot
- of different figures to hide.
- a. Press 5 to return to the GRAPH menu.
