Chapter 7 - Group Properties Specifying a Delimiter

Delimiters do not appear as part of the actual data. For example, if the delimiter is
specified as a comma, the comma in the following text item would be considered a
delimiter, rather than part of the data itself:

If the data does contain the delimiter value, there are ways to format the data so
that both the data and the delimiter are distinguishable. For example, text items
can be enclosed in quotation marks. Or, a release character may be used. For
information on release characters, see Chapter 4 - Type Properties.
