Content

String you want to parse

Filename

Path to a file containing a PDS3

util

A list containing a PDS3 lexer & parser as returned by `getLexerParser()`. Typically not required, but improves performance if parsing many files.

assume_complete

extra_data

Content following 'END'. If assume_complete is F or there is no content after the label, this will be an empty string
