.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 indent
|
||||
.It <space>
|
||||
Output the rest of the line without change.
|
||||
.It 0
|
||||
Output a <newline> character before printing the rest of the line.
|
||||
.It 1
|
||||
Output a <formfeed> character before printing the rest of the line.
|
||||
.It +
|
||||
The trailing <newline> of the previous line is replaced by a <carriage-return>
|
||||
before printing the rest of the line.
|
||||
.El
|
||||
.Pp
|
||||
Lines beginning with characters other than the above are treated as if they
|
||||
begin with <space>.
|
||||
.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.
