       1mlassign 4m22mlist24m 4mvar24m ?4mvar24m...?
              Assign successive elements of a list to specified variables.  If
              there are more variable names than fields, the  remaining  vari-
              ables  are  set to the empty string.  If there are more elements
              than variables, a list of the unassigned elements is returned.

              For example,

                  lassign {dave 100 200 {Dave Foo}} name uid gid longName

              Assigns 4mname24m to ``dave'', 4muid24m to ``100'', 4mgid24m  to  ``200'',  and
              4mlongName24m to ``Dave Foo''.
