.TH ARFF 8
.CT 1 sa_nonmortals
.SH NAME
arff \- read RT11 files
.SH SYNOPSIS
.B arff
[
.I key
]
[
.I name ...
]
.SH DESCRIPTION
.I Arff
reads and writes files
on an RT11 volume,
such as the VAX-11/780 console floppy or 
11/750 console tape.
Its actions are controlled by the
.I key
argument, in the manner of
.IR ar (1).
Other arguments
are the names of files
to be read or written.
.PP
The RT11 filesystem restricts names to the character set
.BR a - z0 - 9.\| ,
and there are no subdirectories.
Filename arguments are trimmed to the last pathname element
and mapped to lower case.
.PP
The key must contain one of the letters
.LR rxdt ,
which mean the same as in
.I ar.
Unlike
.I ar,
however,
.I arff
may reorder files to fit without moving existing files.
.PP
Other key letters are
.TP
v
Verbose.
.TP
.B f
The next argument is the name of the archive instead
of the default
.FR /dev/floppy .
.TP
.B m
Omit the DEC-standard sector interleaving algorithm;
needed when the file isn't a floppy;
e.g. the 11/750 console cassette.
.SH FILES
.F /dev/floppy
.SH BUGS
Floppy errors are handled ungracefully.
.br
The program is too floppy-dependent.
Mapping belongs in the device driver,
or at least shouldn't be the default.

This archive runs on limited infrastructure. Preserving old code on modern bandwidth. Automated agents are requested to crawl responsibly.
