-.Dd June 6, 1993
-.Dt FPR 1
-.Os BSD 4.2
-.Sh NAME
-.Nm fpr
-.Nd print Fortran file
-.Sh SYNOPSIS
-.Nm fpr
-.Sh DESCRIPTION
-.Nm Fpr
-is a filter that transforms files formatted according to
-Fortran's carriage control conventions into files formatted
-according to
-.Ux
-line printer conventions.
-.Pp
-.Nm Fpr
-copies its input onto its output, replacing the carriage
-control characters with characters that will produce the intended
-effects when printed using
-.Xr lpr 1 .
-The first character of each line determines the vertical spacing as follows:
-.Bd -ragged -offset indent -compact
-.Bl -column Character
-.It Blank One line
-.It 0 Two lines
-.It 1 To first line of next page
-.It + No advance
-.El
-.Ed
-.Pp
-A blank line is treated as if its first
-character is a blank. A blank that appears as a carriage control
-character is deleted. A zero is changed to a newline. A one is
-changed to a form feed. The effects of a "+" are simulated using
-backspaces.
-.Sh EXAMPLES
-.Dl a.out \&| fpr \&| lpr
-.Pp
-.Dl fpr \&< f77.output \&| lpr
-.Sh HISTORY
-The
-.Nm fpr
-command
-appeared in
-.Bx 4.2 .
-.Sh BUGS
-Results are undefined for input lines longer than 170 characters.
