To use the Mittelbach/Schoepf font selection scheme with the PLAIN
format, one should first acquire the MZ3 (FONTSEL) package. This
is available from the Heidelberg repository. Send the mail message
to DHDURZ1.bitnet
      GET FONTSEL PACKAGE
if you do not already have the current FONTSEL files.

To create the FORMAT based on PLAIN and containing the FONTSEL macros
invoke
       INITEX plain
At the * prompt issue
       \input plainfsl
You will need a file FONTDEF.TEX based on the ones in the FONTSEL package,
which will be requested by plainfsl. You also need to choose from
oldlfonts.sty, newlfonts.sty and basefont.tex, as for generating
the LaTeX format. At the end, you will requested to supply a file
in place of `anyextra.xyz'. The name of an existing file (perhaps
a system null file) must be supplied here. Only one file is accepted,
so if you wish to include several files, preloaded fonts etc., a
single file which \input's all of the additional files should be
made up. Your version of PLAIN.TEX might include numerous preloaded
fonts which you never use. Any of the \font\preloaded assignments
in PLAIN.TEX may be omitted, so that rarely used fonts are not
included in the format. If no errors occur, the file PLAIN.FMT will
be created in the current directory (one could invoke INITEX &plain
instead of INITEX plain, in which case the created file will have
the name PLAINFSL.FMT). Rename the created FMT file to PLF.FMT and
move it to the FORMATS directory. One then invokes this format by
                         TEX &PLF
followed by the input TeX file name.
