! LaTeX Error: \cal undefined.

[Peter Davis]

I have some LaTeX files I've been using on a PC, with both winTeX and
emTeX, and I've recently moved back to a Unix environment. When I try
to LaTeX these files now, I get:

! LaTeX Error: \cal undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...

l.448 \renewcommand{\cal}
{\protect\pcal}
?

The top of the file looks like this:

\documentclass[12pt]{pfd-article}
\usepackage[dvips]{graphics}
\usepackage{latexsym}
\usepackage{palatino}
\usepackage{fancybox}
\usepackage{fancyhea}
\usepackage{longtabl}
\usepackage{multirow}

Any ideas what could be causing this? It seems to be happening inside
the size12.clo file. I realize that some of the .sty file names will
have to be changed to use long names, but LaTeX hasn't even gotten
there yet.

I vaguely remember seeing something like this in a TeX environment in
which either psnfss wasn't installed correctly or else some
environment variable was incorrectly set.

Thanks very much,

-pd

For {\cal ...} They now insist we say \mathcal{...}
(Note the slight difference in bracketing.)

I see. However, if I fix that, I now get the same error for \mit

I'm using a class file which worked ok a couple of years ago, but now
seems broken. It's actually just a trivial modification of
article.cls intended to use bold sans-serif fonts for the title and
for section headers. Can anyone suggest a better way to accomplish
this instead of creating a custom class file?

Thanks very much for all the help on this.

\mathnormal. \mathit is for text italic in math mode.
Pretty obvious eh?

Again, you are meant to say \mathit .

However, you could try \usepackage{oldlfont} instead;
this re-installs several of these old macro-names.
