Should be a positive integer; if no value is provided, the length is unlimited and
goes to the next delimiter or to the end of the value.
Note
When constructing a reference, if the reference component found is of numeric type, the
length is made up by inserting leading zeros; if it is not, by inserting trailing blanks.
In either case, reference components are truncated if necessary at the right hand side.
When seeking a reference, the length indicates the number of characters which should be
compared. Values longer than this will be regarded as matching, if they start correctly.
delim
(delimiter) supplies a delimiting string following the reference component.
