The name of each file written by \fBdgr2file\fR is file_copy_\fIcycleNbr\fR, where \fIcycleNbr\fR is initially zero and is increased by 1 every time \fBdgr2file\fR closes the file it is currently writing and opens a new one. .PP Upon receiving a \s-1DGR\s0 datagram from \fBfile2dgr\fR, \fBdgr2file\fR extracts the content of the datagram (either a line of text from the file that is being transmitted by \fBfile2dgr\fR or else an \s-1EOF\s0 string indicating the end of that file).
