On Unix records within a text file a separated by <LF> characters. In Windows they are separated by <CR><LF> pairs. This causes problems if you need to read or write to files on a network drive on a Unix system. The StreamFile unit allows you to read and write Unix-style text files while using standard Pascal I/O functions.
