NAME

       lrange - Return one or more adjacent elements from a list

SYNOPSIS

       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.  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]”

EXAMPLES

       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}
