+.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 .
