A Tcl script consists of a series of command invocations. A command invocation is a list of words separated by whitespace and terminated by a newline or semicolon. The first word is the name of a command, which may be built into the language, found in an available library, or defined in the script itself. The subsequent words serve as arguments ...
incr Tcl from the Ground Up by Chad Smith, published in January 2000. This is a complete reference manual for incr Tcl, covering language fundamentals, OO design issues, overloading, code reuse, multiple inheritance, abstract base classes, and performance issues. Despite its breadth, it follows a tutorial, rather than encyclopedic, approach.
Tcl allows both quotes (for interpolated strings) and braces (for raw strings), as in "The quick brown fox" or {The quick {brown fox}}; this derives from the single quotations in Unix shells and the use of braces in C for compound statements, since blocks of code is in Tcl syntactically the same thing as string literals – that the delimiters ...
Expect is an extension to the Tcl scripting language written by Don Libes. [2] The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems.
Strings with unbalanced quotes or braces, or non-space characters directly following closing braces, cannot be parsed as lists directly. You can explicitly split them to make a list. The "constructor" for lists is of course called list. It's recommended to use when elements come from variable or command substitution (braces won't do that).

In object-oriented languages, string functions are often implemented as properties and methods of string objects. In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions.
