The delete is fine; the problem is in the display of the results.
If you use:
put theArray[1] &"*"&theArray[2] &"*"& theArray[3]
...you'll get the empty entry for theArray[2]. The variable theArray
still exists, but there's nothing in that slot.
Yes, this is the problem. I'm storing data in array form in custom
properties, and my problem is after a delete, the remaining elements of the
array are not reordered.
True, the order of elements in an associative array is not maintained
across split and combine, but within the array there is no "order" per
se, just a set of slots that point to memory locations.
If order is important you'll want to use the sort command on the array
keys and access them in that sorted order.
Building the output from the keys of the array will get what you want:
put the keys of theArray into tKeys
sort lines of tKeys -- if the order is important
repeat for each line tKey in tKeys
put "*"& theArray[tKey] after tResult
end repeat
put tResult
From what you're saying, it sounds like I need to put the remaining elements
of the array into a temporary variable and then replace the original array.
Not at all. The array's fine. All you need to do is tailor your output
according to your needs.
It may be helpful to remember that all arrays in LiveCode are
associative arrays. Any keys you use are strings, whether comprised of
alphanumeric or strictly numeric characters.
The slots in an associative array aren't numbered per se, they're named.
Using the keys of the array will show you which names are in use, and
they can be sorted to get any output you need.
