NAME
fpr —
print Fortran file
SYNOPSIS
DESCRIPTION
fpr is a filter that transforms files formatted according to
Fortran's carriage control conventions into files formatted according to
UNIX line printer conventions.
fpr copies its input onto its output, replacing the carriage
control characters with characters that will produce the intended effects when
printed using
lpr(1). The first
character of each line determines the vertical spacing as follows:
Blank |
One line |
0 |
Two lines |
1 |
To first line of next page |
+ |
No advance |
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.
EXAMPLES
a.out | fpr | lpr
fpr < f77.output | lpr
HISTORY
The
fpr command appeared in
4.2BSD.
BUGS
Results are undefined for input lines longer than 170 characters.
