- lindex list index
- Treats list as a Tcl list and returns the index'th
- element from it (0 refers to the first element of the
- list). In extracting the element, lindex observes the
- same rules concerning braces and quotes and backslashes
- as the Tcl command interpreter; however, variable
- substitution and command substitution do not occur. If
- index is negative or greater than or equal to the
- number of elements in value, then an empty string is
- returned.
