urgent help needed: How to use the \jot command?

[Sunrong Gong]

Hi all:

I tried to use the \jot command to adjust the space between
lines in the \eqnarray enviroment but with no success. The
Lamport book is no help on this. I tried something like this:

\begin{eqnarray} {\jot{2mm}
\jot{2mm} and \begin{eqnarray}
...... .....
\end{eqnarray} \end{eqnarray} }

but in both cases latex give error messages "number missing..."
and "illegal unit..."

What is the correct way to use this command? Are there other ways
to adjust the space between lines in the \eqnarray enviroment?

Any help will be greatly appreciated.

\jot is a dimension variable of plainTeX wich LaTeX also uses
and is initially set to 3pt. You can change its value to 2mm
by typing

\jot 2mm or \jot=2mm

or, speaking LaTeX:

\setlength{\jot}{2mm}

But you can also set the interline space explicitly by giving an
optionall parameter to the \\ command

(Eq.1) \\[2mm]
(Eq.2)

OK?
