In the system: +<blockquote> +<pre> +\begin{eqnarray} + a & = & b + c \\ + x & = & y - z +\end{eqnarray} +</pre> +</blockquote> +the spacing around the "=" signs is <em>not</em> that defined in the +metrics for the font from which the glyph comes - it's +<code>\</code><code>arraycolsep</code>, which may be set to some very odd value for reasons +associated with real arrays elsewhere in the document. +<p>The user is far better served by the AMSLaTeX bundle, which +provides an <code>align</code> environment, which is designed with +the needs of mathematicians in mind (as opposed to the convenience of +LaTeX programmers).
