asa
— interpret
carriage-control characters
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⟩.
The asa
utility exits 0 on success,
and >0 if an error occurs.

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

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