7.1.4.3 Delimiters
Delimiters are ASCII characters used to separate fields within a record and to separate
components within fields. Below is a description of the delimiters and how they are
commonly used:
Character Name Used as
| vertical bar Field delimiter
\ Backslash Repeat delimiter
^ Caret Component delimiter
& ampersand Escape delimiter
<CR> carriage return Record delimiter
<CR><LF> carriage return, line feed Record delimiter (alternate form - NOT USED)
7.1.4.3.1 Field Delimiter = Vertical Bar ‘|’
A Field delimiter is a character used to separate fields that are next to each other in a
record. This is also a delimiter for the first Record ID (character that appears in the
beginning of a record) and the next field. According to the 2nd character that appears in
the Message Header Record (record that appears in the front of a message), a Field
delimiter can be defined with an optional character within the Message Header Record;
however, it is recommended that a vertical bar ‘|’ (ASCII 124dec) is used.
7.1.4.3.2 Repeat Delimiter = Backslash ‘\’
When a field is constructed by the same data repeated several times, it is referred to as a
Repeated Field. The delimiter between the repeated items for the Repeated Field is called
the Repeat delimiter. Repeat delimiters can be defined with an optional character within the
Message Header Record; however, it is recommended that a backslash ‘\’ be used.
7.1.4.3.3 Component Delimiter = caret ‘^’
When a field is constructed by several elements, it is referred to as a Component Field. The
delimiter between these elements is the Component delimiter. The Component delimiter can
be defined with an optional character within the Message Header Record; however, it is re-
commended that a caret ‘^’ be used.
7.1.4.3.4 Escape Character = Ampersand ‘&’
An Escape character is provided to indicate a delimiter for the fields that include general
text. When this character occurs in a relevant field, the next character holds a special
meaning (discussed below). An Escape character can be defined with an optional character
within the Message Header Record; however, it is recommended that an ampersand ‘&’ be
used.
7.1.4.3.5 Expression of Special Characters with Escape
Character
If you want to use any of the characters that are predefined as delimiters, within a text, you
can use the following Escape sequence (starting with & and ending with &). When this se-
quence is detected in a field, the corresponding character is set as text character and the
escape sequence is deleted.
