David,
Maybe there are better ways, but here's what I always do when I have an array
with numbered keys...
put the keys of pArray into aKeys
sort lines of aKeys numeric
repeat for each line k in aKeys
//do something with pArray[k]
end repeat
Hope that helps. :)

Ah that explains it. The extents works but I seem to remember for each is
considerably faster

If the array is indexed from 1 with no gaps, you can do
repeat with I = 1 to item 2 of line 1 of the extents of myArray

I’m pretty sure there must be a way to efficiently loop through numerically
indexed
As long as the array is indexed starting at 1 with no gaps it should work by
looping for each element. I just did a quick test to confirm. I built a 100
element array and it looped in order. I deleted 2 keys and then it didn’t. I
then added those 2 missing keys back and it worked again.
I’m pretty sure there must be a way to efficiently loop through numerically
indexed arrays
Repeat for each key and repeat for each element does not seem to sort the keys
in numeric order,. Of course I can get the keys and sort them before repeating
- but is there a more efficient way?
