TeX is a powerful text formatter written by Donald Knuth; like GNU
Emacs, it is free. LaTeX is a simplified input format for TeX,
implemented by TeX macros. It is part of TeX.
Emacs has a special TeX mode for editing TeX input files. It
provides facilities for checking the balance of delimiters and for
invoking TeX on all or part of the file.
TeX mode has two variants, Plain TeX mode and LaTeX mode, which are
two distinct major modes that differ only slightly. These modes are
designed for editing the two different input formats. The command `M-x
tex-mode' looks at the contents of a buffer to determine whether it
appears to be LaTeX input or not; it then selects the appropriate mode.
If it can't tell which is right (e.g., the buffer is empty), the
variable `TeX-default-mode' controls which mode is used.
The commands `M-x plain-tex-mode' and `M-x latex-mode' explicitly
select one of the variants of TeX mode. Use these commands when `M-x
tex-mode' does not guess right.
- TeX EditingSpecial commands for editing in TeX mode.
- TeX PrintCommands for printing part of a file with TeX.
TeX for Unix systems can be obtained from the University of
Washington for a distribution fee.
To order a full distribution, send $140.00 for a 1/2 inch 9-track
tape, $165.00 for two 4-track 1/4 inch cartridge tapes (foreign sites
$150.00, for 1/2 inch, $175.00 for 1/4 inch, to cover the extra
postage) payable to the University of Washington to:
Northwest Computer Support Group, DW-10
University of Washington
Seattle, Washington 98195
Purchase orders are acceptable, but there is an extra charge of $10.00
to pay for processing charges. (The total cost comes to $150 for
domestic sites, $175 for foreign sites).
The normal distribution is a tar tape, blocked 20, 1600 bpi, on an
industry standard 2400 foot half-inch reel. The physical format for
the 1/4 inch streamer cartridges uses QIC-11, 8000 bpi, 4-track
serpentine recording for the SUN. Also, SystemV tapes can be written
in cpio format, blocked 5120 bytes, ASCII headers.
