Split Last Word into New Line

Question

Hello,
Any pointers to below :-
When entering data in column of size say 4000 the last word in the line should not be split if it cud not fit,
if the last word does not fit then it should appear in new line and cursor should be placed at last of the word (if its last word of sentence).
Note that multiline is set to yes and item is text item with form layout, although i have one solution but its not the best one.
Thoughts are appreciated if there is any built in property for this or some other way?

Hello,
This could be the starting point of an algorythme:
SQL> set serveroutput on
SQL>
SQL> DECLARE
  2    LC$c    VARCHAR2(1000);
  3    v       VARCHAR2(1000);
  4    LN$MAX  PLS_INTEGER := 20 ;
  5    i       PLS_INTEGER;
  6  BEGIN
  7    LC$c := 'Here is a text to test the split of a large sentence into multiple sub fields';
  8    LOOP
  9      v := SUBSTR(LC$c, 1, LN$MAX);
10      i := INSTR(v,' ',-1);
11     IF i > 0 AND i < LENGTH(v) THEN
12       v := SUBSTR(v,1,i);
13       LC$c := SUBSTR(LC$C,i+1,1000);
14     ELSE
15       LC$c := SUBSTR(LC$C,LN$MAX+1,1000);
16     END IF ;
17     DBMS_OUTPUT.PUT_LINE('[' || v || ']');
18     EXIT WHEN LENGTH(LC$C) = 0  OR LENGTH(LC$c) <= LN$MAX; 
19    END LOOP;
20    IF LENGTH(LC$c) > 0 THEN
21      DBMS_OUTPUT.PUT_LINE('[' || LC$C || ']');
22    END IF ;
23  END;
