Writing Your First Program on Your Computer

Alright, with the setup out of the way, let's dive into the fun part: writing your first program! We'll use a text editor on your computer to write the code, and then transfer it to your TI-84. This is where you'll really start to see the benefits of programming on your computer.

Choosing a Text Editor

While you could use a basic text editor like Notepad (on Windows) or TextEdit (on macOS), I highly recommend using a more advanced code editor. These editors come with features like syntax highlighting, which makes your code much easier to read, and error checking, which can save you from a lot of frustration. Here are a few popular options:

• Visual Studio Code (VS Code): A free, powerful editor with tons of extensions.
• Sublime Text: A sleek, fast editor with a free trial.
• Atom: Another free, open-source editor from GitHub.

For this guide, I'll assume you're using VS Code, but the principles are the same for any code editor. Download and install VS Code if you haven't already.

Writing the Program Code

Let's start with a simple program that displays "Hello, World!" on your TI-84 screen. Here's the code:

:Disp "HELLO, WORLD!"

Yes, that's it! TI-Basic is pretty straightforward. Here’s a breakdown:

• :: In TI-Basic, a colon is used to start a new line of code.
• Disp: This command tells the calculator to display something on the screen.
• "HELLO, WORLD!": The text you want to display, enclosed in quotes.

Open your text editor and type in this line of code. Save the file with a .txt extension, for example, hello.txt. Make sure to save it in a place where you can easily find it.

Transferring the Program to Your TI-84

Now that you've written your program, it's time to get it onto your calculator. This is where TI Connect CE comes back into play.

1. Open TI Connect CE: Launch the TI Connect CE software on your computer.
2. Select Program Editor: In TI Connect CE, find and select the “Program Editor” or a similar option that allows you to manage programs.
3. Send to Calculator: Drag and drop your hello.txt file into the TI Connect CE window, or use the “Send to Calculator” option. The software will convert the .txt file into a format that your TI-84 can understand.
4. Confirm Transfer: Follow the prompts to confirm the transfer. The calculator will receive the program, and it will be stored in the calculator’s memory.

Once the transfer is complete, you can run the program on your TI-84. Press the PRGM button, select your program (HELLO), and press ENTER. You should see "HELLO, WORLD!" displayed on the screen. Congrats, you've just run your first program written on your computer!

Editing Programs on Your Computer

One of the biggest advantages of programming your TI-84 on your computer is the ability to easily edit your programs. Making changes directly on the calculator can be tedious, but with a computer, it's a breeze.

Modifying Existing Programs

Let's say you want to change the message in your "Hello, World!" program. Instead of retyping the whole thing on your calculator, you can simply open the hello.txt file in your text editor, make the changes, and re-transfer it to your TI-84.

1. Open the Program File: Open the hello.txt file in your text editor.
2. Make Changes: Change the text inside the quotes. For example, you could change it to "HELLO, TI-84!".
3. Save the File: Save the changes to the hello.txt file.
4. Re-transfer the Program: Use TI Connect CE to transfer the updated hello.txt file back to your calculator, overwriting the old version.

Now, when you run the program on your TI-84, it will display the new message. This process is so much faster and more efficient than editing directly on the calculator.

Debugging Tips

Debugging is a crucial part of programming. When your program doesn't work as expected, you need to find and fix the errors. Here are a few tips for debugging TI-Basic programs:

• Check Syntax: Make sure you've typed everything correctly. TI-Basic is very picky about syntax.
• Use Comments: Add comments to your code to explain what each part does. This can help you understand your code later and make it easier to find errors. In TI-Basic, you can use the `` (apostrophe) to start a comment.
• Test Small Sections: Test your program in small sections. Write a little bit of code, transfer it to your calculator, and test it. If it works, add more code and test again. This makes it easier to isolate errors.
• Use Disp Statements: Use Disp statements to display the values of variables at different points in your program. This can help you see what's going on and find errors.

For example:

:Input "ENTER A NUMBER:",A
:A+5→B
:Disp B ;"THIS IS THE VALUE OF B"
:Disp "HELLO, WORLD!"

In this example, the Disp B statement will show the value of B on the screen, helping you debug the program.

Advanced Programming Techniques

Once you're comfortable with the basics, you can start exploring more advanced programming techniques. TI-Basic has a lot to offer, and you can create some pretty impressive programs with it.

Working with Variables

Variables are used to store data in your programs. In TI-Basic, you can use single letters (A-Z) as variables. Here's how to use variables:

:5→A ;STORE 5 IN VARIABLE A
:10→B ;STORE 10 IN VARIABLE B
:A+B→C ;ADD A AND B, STORE THE RESULT IN C
:Disp C ;DISPLAY THE VALUE OF C (WHICH IS 15)

Using Loops

Loops allow you to repeat a block of code multiple times. This is useful for tasks like iterating through lists or performing calculations multiple times. Here's an example of a For loop:

:For(I,1,10) ;START A LOOP THAT RUNS 10 TIMES
:Disp I ;DISPLAY THE VALUE OF I
:End ;END OF THE LOOP

This loop will display the numbers 1 through 10 on the screen.

Conditional Statements

Conditional statements allow you to execute different blocks of code depending on whether a condition is true or false. Here's an example of an If statement:

:Input "ENTER A NUMBER:",A
:If A>0 ;IF A IS GREATER THAN 0
:Then
:Disp "POSITIVE"
:Else
:Disp "NOT POSITIVE"
:End

This program will ask the user to enter a number and then display "POSITIVE" if the number is greater than 0, or "NOT POSITIVE" otherwise.

Creating Menus

Menus can make your programs more user-friendly by providing a list of options for the user to choose from. Here's how to create a menu:

:Menu("MAIN MENU","OPTION 1",1,"OPTION 2",2)
:Lbl 1
:Disp "YOU CHOSE OPTION 1"
:Goto 3
:Lbl 2
:Disp "YOU CHOSE OPTION 2"
:Goto 3
:Lbl 3
:Stop

This program will display a menu with two options: "OPTION 1" and "OPTION 2". When the user selects an option, the corresponding code will be executed.

Best Practices for TI-Basic Programming

To write efficient and maintainable TI-Basic programs, here are some best practices to keep in mind:

• Keep it Simple: TI-Basic is not the most powerful language, so try to keep your programs as simple as possible. Avoid complex algorithms and data structures if you can.
• Use Meaningful Variable Names: While you're limited to single-letter variable names, try to use names that are meaningful. For example, use A for age, S for sum, etc.
• Comment Your Code: Add comments to explain what your code does. This will make it easier to understand and maintain your programs.
• Test Thoroughly: Test your programs thoroughly to make sure they work correctly in all situations.
• Optimize for Speed: TI-Basic can be slow, so try to optimize your code for speed. Avoid unnecessary calculations and use efficient algorithms.
