Hi all,
So, “Now is the time” for me to give:
Luther answer makes my brain overwork and the idea to implement
functions that I need (habit to use) and so here is a
Mid(Source,Start,End) function came to me.
Of course, AppleScript does not let me use the names (words) I want, so
I used others.
The first line ask the StringMid function to display "les", the defined
function StringMid do the job.
"Salut les filles.": Hi girls or Hi girlies…
display dialog my StringMid("Salut les filles.", 7, 3)
-- ********** ********** ********** ********** **********
--
-- “StringMid(StringSource, StartCount, CharCount)” definition:
--
on StringMid(StringSource, StartCount, CharCount)
-- StringSource: the string you want to extract characters from
-- StartCount: the first character to be returned
-- CharCount: the number of characters you want to return
-- TargetString: the stripped string to be returned
-- declare some variables
set TargetString to ""
set StringEnd to 0
set StringLength to 0
-- compute the source string length
set StringLength to count of characters in StringSource
-- compute the string offset
set StringEnd to (StartCount + CharCount) - 1 -- [1]
-- store the wanted string
set TargetString to (characters StartCount thru StringEnd of
StringSource) as string
-- return the wanted string
return TargetString
end StringMid
If there is a possible optimisation, please share.

[1] else I get CharCount + 1 ! That is because StartCount points to 'l',
and I ask for three characters, so StartCount + 3. I think so.
