.SH Name
fpr \- print FORTRAN file
.SH Syntax
.B fpr
.SH Description
The
.PN fpr
filter transforms files formatted according to
FORTRAN's carriage control conventions into files formatted
according to UNIX line printer conventions.
.PP
The
.PN fpr
filter copies its input onto its output, replacing the carriage
control characters with characters that will produce the intended
effects when printed using
.MS lpr 1 .
The first character of each line determines the vertical spacing as follows:
.sp
.if t \{\
.TS
center;
c | l.
Character	Vertical Space Before Printing
_
Blank	One line
0	Two lines
1	To first line of next page
+	No advance
.TE
.\}
.if n \{\
.nf

    |   Character   | Vertical Space Before Printing |

    |     Blank     | One line                       |
    |       0       | Two lines                      |

.fi

.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 Restrictions
Results are undefined for input lines longer than 170 characters.
