.Sh NAME
|
||||
.Nm asa
|
||||
.Nd interpret carriage-control characters
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Ar
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility reads files sequentially, mapping
|
||||
.Tn FORTRAN
|
||||
carriage-control characters to line-printer control sequences,
|
||||
and writes them to the standard output.
|
||||
.Pp
|
||||
The first character of each line is interpreted as a carriage-control
|
||||
character. The following characters are interpreted as follows:
|
||||
.Bl -tag -width "\*[Lt]space\*[Gt]"
|
||||
.It \*[Lt]space\*[Gt]
|
||||
Output the rest of the line without change.
|
||||
.It 0
|
||||
Output a \*[Lt]newline\*[Gt] character before printing the rest of the line.
|
||||
.It 1
|
||||
Output a \*[Lt]formfeed\*[Gt] character before printing the rest of the line.
|
||||
.It +
|
||||
The trailing \*[Lt]newline\*[Gt] of the previous line is replaced by a \*[Lt]carriage-return\*[Gt]
|
||||
before printing the rest of the line.
|
||||
.El
|
||||
.Pp
|
||||
Lines beginning with characters other than the above are treated as if they
|
||||
begin with \*[Lt]space\*[Gt].
|
||||
.Sh EXIT STATUS
|
||||
The
|
||||
.Nm
|
||||
utility exit 0 on success, and \*[Gt]0 if an error occurs.
|
||||
.Sh EXAMPLES
|
||||
To view a file containing the output of a
|
||||
.Tn FORTRAN
|
||||
program:
|
||||
.Dl asa file
|
||||
.Pp
|
||||
To format the output of a
|
||||
.Tn FORTRAN
|
||||
program and redirect it to a line-printer:
|
||||
.Dl a.out | asa | lpr
|
||||
.Sh SEE ALSO
|
||||
.Xr f77 1
|
||||
.Sh STANDARDS
|
||||
The
|
||||
.Nm
|
||||
utility conforms to
|
||||
.St -p1003.2-92
|
||||
and to
|
||||
.St -xcu5 .
