Allen, Tony,

This is my conversation with ChatGPT 4o:

Do you know BASIC09?

Yes, BASIC09 is a variant of the BASIC programming language designed specifically for the OS-9 operating system, which was popular on the Tandy TRS-80 Color Computer (CoCo) in the 1980s. BASIC09 is more structured and powerful than standard BASIC, supporting features like procedures, local variables, structured programming constructs (IF-THEN-ELSE, DO-LOOP), and advanced data types.

It was particularly known for its speed and efficiency compared to other BASIC interpreters of the time, as it was compiled to an intermediate code that ran much faster than standard interpreted BASIC. BASIC09 was widely used by enthusiasts of the OS-9 operating system for developing software with a more modern approach compared to traditional BASIC. 

Do you have a specific question or project related to BASIC09?

Can you write a BASIC09 bubble sort procedure?

Sure! Below is a BASIC09 procedure that implements the bubble sort algorithm. This procedure sorts an array of integers in ascending order.

```basic
PROCEDURE BubbleSort(array, n)
  DIM temp, i, j
  FOR i = 0 TO n - 2
    FOR j = 0 TO n - 2 - i
      IF array(j) > array(j + 1) THEN
        ' Swap array(j) and array(j + 1)
        temp = array(j)
        array(j) = array(j + 1)
        array(j + 1) = temp
      ENDIF
    NEXT j
  NEXT i
END
```

### Explanation
- `array`: The array of integers to be sorted.
- `n`: The number of elements in the array.
- `i` and `j`: Loop indices used to traverse the array.
- `temp`: A temporary variable used to swap elements.

### Usage Example
To use this procedure, you would define your array and call the `BubbleSort` procedure like this:

```basic
DIM numbers(5)
numbers(0) = 34
numbers(1) = 12
numbers(2) = 25
numbers(3) = 16
numbers(4) = 9

BubbleSort(numbers, 5)

FOR i = 0 TO 4
  PRINT numbers(i)
NEXT i
```

This code will sort the `numbers` array in ascending order and print the sorted values. Let me know if you need any further assistance or adjustments!
