Carriage Return/ Line Feed, the end of line characters used in standard PC text files (ASCII decimal 13 10, hex 0D 0A).
In the Mac, only the CR is used; in Unix, only the LF.
In Quaestor CrLf can be created by means of CHR$(13) + CHR$(10) or by means of the Quaestor constant Qcrlf.
When one considers that the computer world could not standardise the code to use to end a simple text line, it is truly a miracle that sufficient standards were agreed upon to support the Internet, which flourishes only because it is a standard.
