I’m trying to change the addresses of the variables once the procedure is done processing the instructions. I have no clue what I’m doing wrong and how to fix it. For example when I input

Gimme X: 12

Gimme Y: 1

Gimme Z: 50

I get this

After biggest, X = 12 Y = 1 Z = 50

when it should be After biggest, X = 50, Y = 50, Z = 50

This is my code so far, any help is greatly appreciated.

program BiggestValue;
#include("stdlib.hhf");

static
    x: int16;
    y: int16;
    z: int16;

procedure biggest(var x: int16; var y: int16; var z: int16); @nodisplay; @noframe;
static
    maxValue: int16;
begin biggest;

    // Load addresses of x, y, and z into registers
    lea(ebx, x);         // ebx = address of x
    lea(ecx, y);         // ecx = address of y
    lea(edx, z);         // edx = address of z

    // Load values pointed by x, y, and z
    mov((type int16 [ebx]), ax);  // ax = value at address x
    mov((type int16 [ecx]), bx);  // bx = value at address y
    mov((type int16 [edx]), cx);  // cx = value at address z

    // Find the maximum value
    mov(ax, maxValue);   // maxValue = value at x
    cmp(bx, maxValue);
    jle skip_y;
    mov(bx, maxValue);   // maxValue = value at y
    skip_y:
    cmp(cx, maxValue);
    jle skip_z;
    mov(cx, maxValue);   // maxValue = value at z
    skip_z:

    // Set x, y, and z to maxValue
    mov(maxValue, (type int16 [ebx]));  // value at address x = maxValue
    mov(maxValue, (type int16 [ecx]));  // value at address y = maxValue
    mov(maxValue, (type int16 [edx]));  // value at address z = maxValue

end biggest;

begin BiggestValue;

    // Get input from the user
    stdout.put("Gimme X: ");
    stdin.get(x);
    stdout.put("Gimme Y: ");
    stdin.get(y);
    stdout.put("Gimme Z: ");
    stdin.get(z);

    // Call the biggest procedure
    biggest(x, y, z);

    // Print the results
    stdout.put("After biggest, X = ", x, " Y = ", y, " Z = ", z, nl);

end BiggestValue;
