The code |< occurring at the beginning of a search string ensures that the entire search string only matches text occurring at the beginning of a line.
Similarly, the code |> occurring at the end of a search string ensures that the entire search string only matches text occurring at the end of a line.
Unlike |L and |N, |< and |> do not include the “newline” character(s) in the matched text. This is an important distinction when performing a replacement - with |L and |N the “newline” character(s) will be replaced; with |< and |> they are not replaced. With {CONFIG, File Handling, File type} set to Record mode, these codes match the beginning/end of a record.
