I have a requirement to use LaTeX to typeset a document with many lists,
most of which have a title, eg

Something procedure
1. do something
2. do something more
3. finish it

but of course

\begin{itemize}
\textbf{Something procedure}
\item do something
\item do something more
\item finish it
\end{itemize}

issues a "Something's wrong--perhaps a missing \item" error.

I can think of probably half a dozen ways round the requirement for an
\item immediately following a \begin{<list>}, but I can't seem to find
any package for handling this format. I'd like to keep the title within
the scope of the list environment for subsequent markup reuse.

Has anyone tackled this?

Howdy,

How about

\noindent\textbf{Something procedure}
\begin{itemize}
\item do something
\item do something more
\item finish it
\end{itemize}

with the title starting a new paragraphwith no indent which will add a bit of
space under the title.

Good Luck,
Herb Schulz

Well you could put the title in a hbox, that wouldn't switch into
hmode and so avoid the error:
\begin{itemize}
\hbox{\textbf{Something procedure}}
\item do something
\item do something more
\item finish it
\end{itemize}

But on the whole, I would say it would be better to define an
environment, e.g.

\documentclass{article}
\usepackage{enumitem}
\NewDocumentEnvironment{enumtitle}{m}
{\textbf{#1}
\begin{enumerate}[beginpenalty=10000]% no page break after title
}{\end{enumerate}}

\begin{document}
\begin{enumtitle}{My title}
\item a
\item b
\item c
\end{enumtitle}

\end{document}

That is certainly one solution, but I'd like to keep the title within
the scope of the list environment for subsequent markup reuse.

Currently (for description lists) I am using

\newcommand{\listtitle}[1]{%
\item[\relax]\hspace*{-\labelsep}\textbf{\sffamily#1}}

eg

\begin{description}
\listtitle{Something procedure}
\item[start] do something
\item[more] do something more
\item[finish] finish it
\end{description}

I'll be working on it for itemize and enumerate (with enumitem, I suspect).

Thank you, that would work.

Yes, that also works, but I'm not a big fan of creating new environments
for something that existing environments ought to be able to handle
transparently. It makes it easier for users if they can just continue to
use the normal list environments, but give one a title when they need to.
