FPR(1) — USER COMMANDS

NAME

fpr − print FORTRAN file

SYNOPSIS

fpr

DESCRIPTION

fpr reads one file and writes another file. It transforms a file formatted by FORTRAN carriage-control conventions into a file formatted by 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

0two lines

1to first line of next page

+no advance

A blank line (that is, an empty line) is treated as if its first character is a blank. A blank line that appears as a carriage control character only is deleted.

A zero is changed to a newline.

A one is changed to a form feed.

A plus is simulated using backspaces.

Note that fpr is known as asa in UNIX System V.

EXAMPLES

        write(∗,’(" Blank")’)
        write(∗,’("0Zero ")’)
        write(∗,’("+    Plus ")’)
        write(∗,’("1One ")’)
        end

Example 1. With actual files:

a.out > MyOutputFile
fpr < MyOutputFile | lpr

Example 2. With only pipes:

a.out | fpr | lpr Both of the above examples produce two pages of output. Page 1:

Blank

ZeroPlus
