Need advice on math inside @tex ... @end tex |

Not a bug report, but a request for advice.
In the manual I'm writing, I would like to have some multiline math
formulas come out nicely. I would like to write:
@tex
$$
\begin{array}{l}
a = \min(S_1,\ldots,S_n) \\
b = \max(S_1+D_1,\ldots,S_n+D_n) \\
R_{ij} = \left\{\begin{array}{ll}
R_j, &\hbox{\ if \ } S_j \leq i < S_j+D_j \\
0, &\hbox{\ otherwise} \\
\end{array}
\right. \\
\end{array}
$$
@end tex
but TeX chokes on \begin{array}:
! Undefined command @begin {array}{l}.
\next ...\errmessage {Undefined command @begin #1}
}\else \csname
#1\endcsnam...
l.978 \begin{array}{l}
I understand that Texinfo redefines \begin and \end. I've tried a
great many times without success to add lines to texinfo.tex, saving
the original definition of \begin and \end. But perhaps \begin and
\end are not TeX commands at all; perhaps \begin{ENV} ... \end{ENV} is
a TeX idiom.
Anyway, any help to achieve what I want is greatly appreciated.
