Using applescript with Filemaker I can make a string of found image
record names such as this:
"1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg, 6969.jpg."
What I want to do is delete the last comma and insert an "&" into the
string to make:
"1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg & 6969.jpg."
I assume that I use text item deliminators but not sure how as there
are multiple ", " in the string and record names will vary with each
use of the script. Any suggestions?
You can count back from the end of a list using negative indices,
Clive:
--------
set t to "1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg, 6969.jpg."
set text item delimiters to ", "
set t to t's text 1 thru text item -2 & " & " & t's text item -1
set text item delimiters to {""}
t --> "1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg & 6969.jpg."

I like reverse of and rest of! No one else has shown this technique so
I'll include it for completeness:
set s to "1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg, 6969.jpg."
set text item delimiters to ", "
set t to reverse of (text items of s)
return "" & (reverse of (rest of t)) & " & " & item 1 of t
--> "1234.jpg, 5678.jpg, 4444.jpg, 5555.jpg, 9876.jpg & 6969.jpg."
