Hi Ian,
When you delete items, the number of items gets smaller while the
variable that counts the items goes up. At some point, you're trying
to delete items that don't exist. Use "down to" to avoid this:
repeat with x = number of lines of myList down to 1
delete line x of myList
end repeat
(in this simple example, you can also use "delete last item", obviously)
Best,
Mark

Hi all
I have a text file of 60 or so return delimited lines each containing
17 comma delimited items. I wrote a script to read the file into a
variable called theImportedData, delete 2 records, alter a 3rd,
display the results in a field and then save the file again.
I came up with the followiing two handlers. Both are executed by Rev
Media but removeFields1 doesn't do anything! ie the delete lines do
not alter the file. removeFields2 does what its supposed to do.
<snip script>
Am I missing something? I think I must because I can't see what is
wrong with the 1st script -- and Rev doesn't find a problem either
because it executes without error. The data in the variable is just
untouched and gets saved again intact.
I'm quite happy to use the 2nd script but I'm curious as to why the
first one doesn't work.
Thanks
Ian McKnight
