lindex(TCL)


lindex -- retrieve an element from a list

Syntax

lindex list index

Description

This command treats list as a Tcl list and returns the element which is index elements from the beginning of the list (for example, 0 refers to the first element, 1 to the second, and so on). In extracting the element, lindex observes the same rules concerning braces, quotes, and backslashes as the Tcl command interpreter; however, variable substitution and command substitution do not occur. If index is negative, greater than or equal to the number of elements in value, then an empty string is returned. If index has the value end, it refers to the last element in the list.
