ASA(1)

NAME
asa, fpr - interpret carriage-control characters

SYNOPSIS
asa [file ...]
fpr [file ...]

DESCRIPTION
The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to the standard output.

The first character of each line is interpreted as a carriage-control character. Additionally, the following characters are interpreted as shown:

<space>
    Output the rest of the line without change.

0   Output a newline (‘\n’) character before printing the rest of the line.

1   Output a <formfeed> character before printing the rest of the line.

+   The trailing newline (‘\n’) of the previous line is replaced by a carriage-return (‘\r’) before printing the rest of the line.

Lines beginning with characters other than the above are treated as if they begin with a space (‘ ’).

EXIT STATUS

EXAMPLES
To view a file containing the output of a FORTRAN program:

    $ asa file

To format the output of a FORTRAN program and redirect it to a line-printer.

    $ a.out | asa | lpr

STANDARDS
The asa utility is compliant with the p1003.1-2008 specification, though its presence is optional.

The fpr utility is deprecated and its use should be restricted.
