Hi Alex,

An item is a string of chars delimited by a specified delimiter 
character.  All the characters up to the first delimiter character 
(or the end of the string, whichever comes first) constitute the 
first item.  If there are no characters before the first delimiter, 
the first item is empty; if there are no characters after the last 
delimiter, there are no more items.

Perhaps it would help to consider items as lines (ie: the 
itemDelimiter = return).

the number of lines of "This is a line" = the number of lines of 
"This is a line"&return

the number of lines of return&"This is line 2" = the number of lines 
of return&"This is line 2"&return
