Using LATEX 2.09

The old LATEX 2.09 system is no longer distributed with . LATEX users should seriously consider switching to the new LATEX; it can typeset LATEX 2.09 documents in ``compatibility'' mode. If you have the old LATEX system from an earlier version of and you want to use it alongside the new LATEX, then carry out these steps:
  1. Delete all log files for your existing LATEX documents so that won't get the wrong format by looking in a log file.
  2. Edit the Default config file and insert "New LaTeX" and "Old LaTeX" anywhere in the list of config files.
  3. Take the LaTeX sub-folder out of your old TeX-inputs folder, rename it Old LaTeX and put it next to (not inside) the new TeX-inputs folder. If you want to store the Old LaTeX folder somewhere else, or use a different name, then you'll have to change the appropriate path in the Old LaTeX config file.
  4. Build OldLaTeX.fmt (no space in the file name!):
    1. Start up and select Old LaTeX from the Config menu.
    2. Run INITEX, type ``lplain\dump'' and hit Return.
    3. Save the format as OldLaTeX.fmt in the TeX-formats folder.
Before typesetting a LATEX 2.09 document you must remember to select Old LaTeX from the Config menu, and before typesetting a new LATEX document you must select New LaTeX.
