probably any sort algorithm you want, but there are limits to the arrays, only 1d. Can use loops and swap values to sort.
something like this should swap:
if arr[x]<arr[y] then (
temp := arr[y];
arr[y] := arr[x];
arr[x] := temp;
);
look up loops, and you will probably want a flag that a swap has occurred, so when none are performed, you know that you are done.

| Bubble sort probably would work. I haven't done one in a few years (okay, a lot of years). |

See my PPT presentations using bubble sort algorithm at http://www.sfarea.org/12201.html - http://www.sfarea.org/12201.html
For arrays under 445 rows, see Nov 2008 meeting (easy)
 For arrays from 1 to 1000 rows due to 99,999 loop limitations,
see Oct 2010 meeting (hard but rigorous)  ------------- joelum |
