@ Here is a table of all the productions.  Each production that
combines two or more consecutive scraps implicitly inserts a {\tt \$}
where necessary, that is, between scraps whose abutting boundaries
have different |mathness|.  In this way we never get double {\tt\$\$}.

% The following kludge is needed because \newcount, \newdimen, and \+
% are "\outer" control sequences that cannot be used in skipped text!
\fi \newcount\prodno \newdimen\midcol \let\+\relax \ifon

\def\v{\char'174} 
\mathchardef\RA="3221 % right arrow
\mathchardef\BA="3224 % double arrow

A translation is provided when the resulting scrap is not merely a
juxtaposition of the scraps it comes from.  An asterisk$^*$ next to a scrap
means that its first identifier gets an underlined entry in the index,
via the function |make_underlined|.  Two asterisks$^{**}$ means that both
|make_underlined| and |make_reserved| are called; that is, the
identifier's ilk becomes |raw_int|.  A dagger \dag\ before the
production number refers to the notes at the end of this section,
which deal with various exceptional cases.

We use \\{in}, \\{out}, \\{back}, \\{bsp}, and \\{din} as shorthands for
|indent|, |outdent|, |backup|, |break_space|, and |dindent|, respectively.

\dag{\bf Notes}
\yskip
Rules 35, 117: The |exp| must not be immediately followed by |lpar|, |lbrack|,
|exp|, or~|cast|.

Rule 48: The |exp| or |int_like| must not be immediately followed by |base|.

Rule 76: The |force| in the |stmt| line becomes \\{bsp} if \.{CWEAVE} has
been invoked with the \.{-f} option.

Rule 78: The |define_like| case calls |make_underlined| on the following scrap.

Rule 94: The |new_like| must not be immediately followed by |lpar|.

Rule 99: The |new_exp| must not be immediately followed by |raw_int|,
|struct_like|, or |colcol|.

Rule 110: The |raw_int| must not be immediately followed by |langle|.

Rule 111: The operator after |operator_like|
must not be immediately followed by a |binop|.

Rule 114: The |operator_like| must not be immediately followed by
|raw_ubin|.

Rule 123: The mathness of the |colon| or |base| changes to `yes'.

Rules 153, 154: |make_reserved| is called only if \.{CWEAVE} has been invoked
with the \.{+t} option.
