@node Syntax Tables, Abbrevs, Searching and Matching, Top
table. This is for the sake of C++. Each style of comment syntax has
its own comment-start sequence and its own comment-end sequence. Each
comment must stick to one style or the other; thus, if it starts with
-the comment-start sequence of style ``b'', it must also end with the
-comment-end sequence of style ``b''.
+the comment-start sequence of style ``b,'' it must also end with the
+comment-end sequence of style ``b.''
The two comment-start sequences must begin with the same character; only
the second character may differ. Mark the second character of the
the current buffer.
@end defun
-@defmac with-syntax-table @var{table} @var{body}...
-@tindex with-syntax-table
+@defmac with-syntax-table @var{table} @var{body}@dots{}
This macro executes @var{body} using @var{table} as the current syntax
table. It returns the value of the last form in @var{body}, after
restoring the old current syntax table.
@cindex parse state
The fifth argument @var{state} is a ten-element list of the same form
-as the value of this function, described below. (It is OK to omit the
-last two elements of this list.) The return value of one call may be
-used to initialize the state of the parse on another call to
-@code{parse-partial-sexp}.
+as the value of this function, described below. The return value of
+one call may be used to initialize the state of the parse on another
+call to @code{parse-partial-sexp}.
The result is a list of ten elements describing the final state of
the parse:
@enumerate 0
@item
-The depth in parentheses, counting from 0.
+The depth in parentheses, counting from 0. @strong{Warning:} this can
+be negative if there are more close parens than open parens between
+the start of the defun and point.
@item
@cindex innermost containing parentheses
@item
What kind of comment is active: @code{nil} for a comment of style
``a'' or when not inside a comment, @code{t} for a comment of style
-``b'', and @code{syntax-table} for a comment that should be ended by a
+``b,'' and @code{syntax-table} for a comment that should be ended by a
generic comment delimiter character.
@item
Internal data for continuing the parsing. The meaning of this
data is subject to change; it is used if you pass this list
as the @var{state} argument to another call.

@end enumerate
-Elements 0, 3, 4, 5, 7 and 9 are significant in the argument
-@var{state}.
+Elements 1, 2, and 6 are ignored in the argument @var{state}. Element
+8 is used only to set the corresponding element of the return value,
+in certain simple cases. Element 9 is used only to set element 1 of
+the return value, in trivial cases where parsing starts and stops
+within the same pair of parentheses.
@cindex indenting with parentheses
This function is most often used to compute indentation for languages
@end defun
@defvar multibyte-syntax-as-symbol
-@tindex multibyte-syntax-as-symbol
If this variable is non-@code{nil}, @code{scan-sexps} treats all
non-@acronym{ASCII} characters as symbol constituents regardless
of what the syntax table says about them. (However, text properties
This table gives the value of @var{syntax-code} which corresponds
to each syntactic type.

@end defun
@defun make-category-table
-@tindex make-category-table
This creates and returns an empty category table. In an empty category
table, no categories have been allocated, and no characters belong to
any categories.
