This is true. And it's also worth noting that this might surprise you  
when using negative indices.
So as well as Jims counting examples,

get item -1 of "a,b," --  returns "b"

whereas when getting and setting items by positive index

get item 3 of "a,b," -- returns empty (as you'd expect)

put "a,b," into tLine
put "d" into item 4 of tLine
-- leaves tLine as: "a,b,,d"


Best,
