Ever written a long program and found yourself scrolling endlessly to find a specific line? Or maybe you just want a quick overview of your code? Look no further than the LIST
command! This handy tool lets you display your BASIC program code right on your Commodore 64's screen. It's like having a magnifying glass for your code, making it easy to inspect, debug, and admire your programming prowess!
Syntax

Where:
- <start line>
(Optional): The line number where you want the listing to begin.
- <end line>
(Optional): The line number where you want the listing to end.
Applications
The LIST
command is your go-to tool for:
- Reviewing your code: Get a quick overview of your entire program or focus on specific sections.
- Debugging: Examine line numbers, identify typos, and spot logical errors.
- Modifying code: Use
LIST
to quickly locate the lines you need to change. - Printing your code: Connect a printer and use
CMD
to send the output ofLIST
to create a hard copy of your program.
Code Examples
1. Listing the Entire Program:
10 X=5
20 LIST
This will display all the lines of your BASIC program on the screen.
2. Listing a Specific Range:
10 REM This line is shown
20 REM This line too
30 REM And this one
40 REM But this line no
50 LIST 10-30
This will list only the lines between 10 and 30, inclusive.
3. Listing from a Specific Line:
10 REM This line is not shown
20 REM This line yes
30 REM This one
40 REM And this one
50 LIST 20- : REM and this one too
This will list all lines from line 100 to the end of the program.
4. Listing to a Specific Line:
10 LIST -50
This will list all lines from the beginning of the program up to line 50.
LIST in the Wild: The Code Reviewer's Best Friend
