akgul@TRBILUN.BITNET (Mustafa Akgul) (03/28/91)
I found a small bug in oldlfont.sty of AMS distribution
of the New Font Selection Scheme of FMi & RS.
If you try to load oldlfont.sty at dump time you will get
an error message stating that `\@undefined' is really UNDEFINED
at that point. It is defined in LaTeX.tex which is read later.
To remedy one should change the line
\@ifundefined{ds@oldlfont}{\let\ds@oldlfont\@empty}{\endinput}
with
\expandafter\ifx\csname ds@oldlfont\endcsname\relax
\let\ds@oldlfont\@empty \else \endinput \fi
and everything works fine.
When you use fontdef.ori, preload.min and modified
oldlfont.sty ( which is called oldlfont.xxx by me),
you will get essentially the lplain.fmt with added
capacity to switch to new font selection scheme.
You only need to pay in time for the loading of actual fonts,
which is mainly minimal.
I have compared the size of this .fmt, say lams0, and lplain.fmt
in various environment. Here are the results:
Environment lplain lams0 plain
ctex 2.991 on SUN4 459K 308K 246K
ctex 2.991 on SUN3 492K 341K 274K
TeX 3.1 on DG MV20000 AOS/VS 583K 432K 335K
SB30TEX on XT 283K 213K 140K
ctex has main memory of 100K and TeX 3.1 has 112K main memory,
several other parameters are also increased.
Clearly it pays to switch to new font selection scheme even if
you do not use it. These is important especially if you do not
have bigTeX at your location.

For convience to some of the readers I am including oldlfont.xxx
