Sorting a multidimensional array

[Bob Sneidar]

Consider however that you can get the keys of an array and sort them as an index to the array. 

put the keys of myArray into theKeys
sort theKeys ascending numeric
repeat for each line theCurrentKey in theKeys
  put myArray [theCurrentKey] into theValue
  — do something with theValue
end repeat

If that serves your purpose, it’s easier *and* faster.
