The default setting is RecordSeparators. With this setting, each complete line of input on any computer system is considered as a record.
Strings used as record separators may contain several characters.
With the option setting NullRecords->False, any number of record separators may appear between any two successive records.
RecordSeparators specifies that everything is to be included in a single record.
RecordSeparators specifies different left and right separators for records. When there are nested left and right separators, records are taken to be delimited by the innermost balanced pairs of separators.
Text that does not appear between left and right separators is discarded.
