.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.
