.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.
