For more information about general sequence and array predicates,
see @ref{Sequences Arrays Vectors}, and @ref{Arrays}.
@node Creating Strings
@section Creating Strings
+@cindex creating strings
+@cindex string creation
The following functions create strings, either from scratch, or by
putting strings together, or by taking them apart.
@node Modifying Strings
@section Modifying Strings
+@cindex modifying strings
+@cindex string modification
The most basic way to alter the contents of an existing string is with
@code{aset} (@pxref{Array Functions}). @code{(aset @var{string}
@node Text Comparison
@section Comparison of Characters and Strings
@cindex string equality
+@cindex text comparison
@defun char-equal character1 character2
This function returns @code{t} if the arguments represent the same
@node Motion and Syntax
@section Motion and Syntax
+@cindex moving across syntax classes
+@cindex skipping characters of certain syntax
This section describes functions for moving across characters that
have certain syntax classes.
@node Parsing Expressions
@section Parsing Expressions
+@cindex parsing expressions
+@cindex scanning expressions
This section describes functions for parsing and scanning balanced
expressions. We will refer to such expressions as @dfn{sexps},
@node Motion via Parsing
@subsection Motion Commands Based on Parsing
+@cindex motion based on parsing
This section describes simple point-motion functions that operate
based on parsing expressions.
@node Position Parse
@subsection Finding the Parse State for a Position
+@cindex parse state for a position
For syntactic analysis, such as in indentation, often the useful
thing is to compute the syntactic state corresponding to a given buffer
@node Control Parsing
@subsection Parameters to Control Parsing
+@cindex parsing, control parameters
@defvar multibyte-syntax-as-symbol
If this variable is non-@code{nil}, @code{scan-sexps} treats all
@node Buffer Contents
@section Examining Buffer Contents
+@cindex buffer portion as string
This section describes functions that allow a Lisp program to
convert any portion of the text in the buffer into a string.
@node Examining Properties
@subsection Examining Text Properties
+@cindex examining text properties
+@cindex text properties, examining
The simplest way to examine text properties is to ask for the value of
a particular property of a particular character. For that, use
@node Changing Properties
@subsection Changing Text Properties
+@cindex changing text properties
+@cindex text properties, changing
The primitives for changing properties apply to a specified range of
text in a buffer or string. The function @code{set-text-properties}
@node Property Search
@subsection Text Property Search Functions
+@cindex searching text properties
+@cindex text properties, searching
In typical use of text properties, most of the time several or many
consecutive characters have the same value for a property. Rather than
@node Substitution
@section Substituting for a Character Code
+@cindex replace characters in region
+@cindex substitute characters
The following functions replace characters within a specified region
based on their character codes.
@node Variables with Restricted Values
@section Variables with Restricted Values
+@cindex lisp variables defined in C, restrictions
Ordinary Lisp variables can be assigned any value that is a valid
Lisp object. However, certain Lisp variables are not defined in Lisp,
@node Generalized Variables
@section Generalized Variables
+@cindex generalized variable
+@cindex place form
A @dfn{generalized variable} or @dfn{place form} is one of the many places
in Lisp memory where values can be stored. The simplest place form is
a regular Lisp variable. But the @sc{car}s and @sc{cdr}s of lists, elements
@node Recombining Windows
@section Recombining Windows
+@cindex recombining windows
+@cindex windows, recombining
When deleting the last sibling of a window @var{W}, its parent window
is deleted too, with @var{W} replacing it in the window tree. This
