lindex(n) Tcl Built-In Commands lindex(n)

NAME
lindex - Retrieve an element from a list
SYNOPSIS
lindex list index
_________________________________________________________________
DESCRIPTION
This command 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. If index has the value end, it refers to the last element in the list, and end-integer refers to the last
element in the list minus the specified integer offset.
