16 List must be a valid Tcl list. This command will return a new list
17 consisting of elements first through last, inclusive. First or last
18 may be end (or any abbreviation of it) to refer to the last element of
19 the list. If first is less than zero, it is treated as if it were
20 zero. If last is greater than or equal to the number of elements in
21 the list, then it is treated as if it were end. If first is greater
22 than last then an empty string is returned. Note: ``lrange list first
23 first'' does not always produce the same result as ``lindex list
24 first'' (although it often does for simple fields that aren't enclosed
25 in braces); it does, however, produce exactly the same results as
26 ``list [lindex list first]''

29 Selecting the first two elements:
30 % lrange {a b c d e} 0 1
31 a b
32
33 Selecting the last three elements:
34 % lrange {a b c d e} end-2 end
35 c d e
36
37 Selecting everything except the first and last element:
38 % lrange {a b c d e} 1 end-1
39 b c d
40
41 Selecting a single element with lrange is not the same as doing so with
42 lindex:
43 % set var {some {elements to} select}
44 some {elements to} select
45 % lindex $var 1
46 elements to
47 % lrange $var 1 1
48 {elements to}
