The kicker is, I do NOT want to use ArraySort() or any other built in MQL function. I want to do this manually in MQL(4). I have a reason, but I need to figure out the basics first.

Thanks.

Maybe this helps:

Inserted Code
#property strict
 
void OnStart()
{
   int arr[] = {21,2,8,1,0,58,96,3};   
   int n = ArraySize(arr);
   int save;
   int i,j;

   //ascending order
   for(i=0;i<n;i++)
   {        
        for(j=i+1;j<n;j++)
        {
            if(arr[i]>arr[j])
            {
                save  = arr[i];
                arr[i]= arr[j];
                arr[j]= save;
            }
        }
   }
    
   string proof = "";
   for(i=0;i<n;i++)
      proof += arr[i]+", ";
       
   Print(proof);   
   return;
}
