       lrange - Return one or more adjacent elements from a list


       lrange list first last


       List must be a valid Tcl list.  This command will return a new list consisting of elements
       first through last, inclusive.  The index values first and last are interpreted  the  same
       as  index  values  for  the  command  string index, supporting simple index arithmetic and
       indices relative to the end 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 first” does not always produce the same result as
       “lindex list first” (although it often does for simple fields that  are  not  enclosed  in
       braces); it does, however, produce exactly the same results as “list [lindex list first]


       Selecting the first two elements:

              % lrange {a b c d e} 0 1
              a b

       Selecting the last three elements:

              % lrange {a b c d e} end-2 end
              c d e

       Selecting everything except the first and last element:

              % lrange {a b c d e} 1 end-1
              b c d

       Selecting a single element with lrange is not the same as doing so with lindex:

              % set var {some {elements to} select}
              some {elements to} select
              % lindex $var 1
              elements to
              % lrange $var 1 1
              {elements to}
