lrange tcl

Overview

Return one or more adjacent elements from a list

Syntax

lrange list first last

Description

List must be a valid Tcl list. This command will return a new list consisting of elements first through last, inclusive. Last may be end (or any abbreviation of it) to refer to the last element of the list. If first is less than zero, it is treated as if it were zero. If last is greater than or equal to the number of elements in the list, then it is treated as if it were end. If first is greater than last then an empty string is returned.

Note: "lrange list first firs" does not always produce the same result as "lindex list first" (although it often does for simple fields that aren't enclosed in braces); it does, however, produce exactly the same results as "list [lindex list first]"
