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”).
