A blank that appears as a carriage control 70character is deleted. A zero is changed to a newline. A one is 71changed to a form feed. The effects of a "+" are simulated using 72backspaces. 73.Sh EXAMPLES 74.Dl a.out \&| fpr \&| lpr 75.Pp 76.Dl fpr \&< f77.output \&| lpr 77.Sh HISTORY 78The 79.Nm fpr 80command 81appeared in 82.Bx 4.2 . 83.Sh BUGS 84Results are undefined for input lines longer than 170 characters. 85
