I think we need a little more information here, maybe a sample value
for $value4. Split, though, doesn't add anything; it removes the
delimiter. If you have:
$value4 = "one\ttwo\tthree\tfour\tfive" ;
@array3=split(/\t/, $value4) ;
returns @array3 = ["one", "two", "three", "four", "five"]
The delimiter is never included in the returned data. If you
questions is really "what happens when there is a trailing delimiter,
or an empty field in the data?", the answer is, trailing delimiters
are ignored, otherwise empty strings are returned. So if
$value4 = "\tone\t\ttwo\tthree\t\tfour\tfive\t" ;
then
@array3 = ["", "one", "", "two", "three", "", "four", "five"]
If you need some other behavior, you need to constuct a more complex
regex for split, but simple adding quotes doesn't change the behavior.
