NAME

asa —

interpret carriage-control characters

SYNOPSIS

asa [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. The following characters are interpreted as follows:

⟨space⟩: Output the rest of the line without change.
0: Output a ⟨newline⟩ character before printing the rest of the line.
1: Output a ⟨formfeed⟩ character before printing the rest of the line.
+: The trailing ⟨newline⟩ of the previous line is replaced by a ⟨carriage-return⟩ before printing the rest of the line.

Lines beginning with characters other than the above are treated as if they begin with ⟨space⟩.

EXIT STATUS

The asa utility exits 0 on success, and >0 if an error occurs.

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 conforms to IEEE Std 1003.1-2001 (“POSIX.1”).
