A blank that appears as a carriage control 43character is deleted. A zero is changed to a newline. A one is 44changed to a form feed. The effects of a "+" are simulated using 45backspaces. 46.Sh EXAMPLES 47.Dl a.out \&| fpr \&| lpr 48.Pp 49.Dl fpr \&< f77.output \&| lpr 50.Sh HISTORY 51The 52.Nm fpr 53command 54appeared in 55.Bx 4.2 . 56.Sh BUGS 57Results are undefined for input lines longer than 170 characters. 58
