REM: Your Code's Storyteller
Tired of cryptic code that even you can't decipher a week later? Let me introduce you to REM, your code's personal storyteller! This unassuming command is your secret weapon for adding comments, explanations, and even a touch of personality to your Commodore 64 BASIC programs. Think of it as the friendly narrator guiding you (and others!) through your code's twists and turns.
Syntax
REM <your comment>
or (if the comment is on the same line as code)
<your code> :REM <your comment>
Where:
- <your comment>: Any text you want to include as a comment. It can be a brief explanation, a reminder, a joke, or anything else you desire!
Applications
The REM command is indispensable for:
- Documenting your code: Explain the purpose of variables, functions, and complex algorithms, making your code easier to understand and maintain.
- Debugging: Temporarily disable sections of code by "commenting them out" using
REMto isolate issues. - Organizing your code: Use comments to create sections, headings, and visual separators to make your program more readable.
- Adding personality: Inject some humor or creativity into your code with funny remarks or personal notes.
Code Examples
1. Simple Comment:
10 REM This program calculates the area of a circle
20 INPUT "Enter radius: "; R
30 LET PI = 3.14
40 A = PI * R * R
50 PRINT "Area: "; A
The comment on line 10 briefly describes the purpose of the program.
2. Commenting Out Code:
10 REM PRINT "This line is disabled"
20 PRINT "This line is active"
The REM command on line 10 effectively disables the PRINT statement, preventing it from being executed.
3. Adding a Personal Touch:
100 REM And now for the grand finale... (drumroll please!)
110 PRINT "Thank you for using my program!"
Here, a playful comment adds a touch of personality to the program.
