Integrate html tags in a string and display it in a multiline text area

Question

Hi ABAPers!!
First of all let me tell you that I'm working in ACCENTURE Casablanca(Morocco) and this is my first Job in my career.
I'm working on an ALV OO, the program consists on creating an ALV using OO, In my selection screen there's a parameter of type ddobjname I provide the name of table and it returns the table's fields in another dynpro (screen0100), To do this I used the FM: 'DDIF_FIELDINFO_GET' then I append the internal table returned in another one to add the field CB (CheckBox), and I add a button in the toolbar, the function of this button is to generate a MySQL script To create the table provided by the user in my parameter (Screen 1000), but the fields of this table(MySQL) in the generated script are only the selected ones by cheking the checkbox in the ALV.
I store my script in a string.
My problem is that I want to show my script in a text area, but I don't know how to create a multiline text area!!
And I want to use HTML tags in my string.
I don't want to my string like this :
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI ( CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY , FLTIME INT ( 10 ) , DEPTIME DATETIME ( 6 ) , DISTANCE DOUBLE ( 9 ) , FLTYPE VARCHAR ( 1 ));
But I want it to be shown like  this:
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI (
CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY ,
FLTIME INT ( 10 ) ,
DEPTIME DATETIME ( 6 ) ,
DISTANCE DOUBLE ( 9 ) ,
FLTYPE VARCHAR ( 1 ));
Thanks in advance

Hi again!!
You know what!! let's forget the HTML and focuse on what I want to show.
As I told you, I've a string which contains my script.
I don't want that it will be shown as a simple line like this :
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI ( CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY , FLTIME INT ( 10 ) , DEPTIME DATETIME ( 6 ) , DISTANCE DOUBLE ( 9 ) , FLTYPE VARCHAR ( 1 ));
But I want it to be shown as follows:
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI (
CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY ,
FLTIME INT ( 10 ) ,
DEPTIME DATETIME ( 6 ) ,
DISTANCE DOUBLE ( 9 ) ,
FLTYPE VARCHAR ( 1 ));
and finally I want to show it in a multiline text area.
Plz what shud I do?!!! If possible I need a piece of code.
PS : I create a HTML Viewer using this code :
DATA : go_conteneur          TYPE REF TO cl_gui_docking_container,
             go_controle_html    TYPE REF TO cl_gui_html_viewer.                 
  CREATE OBJECT go_conteneur                     
    EXPORTING                                    
      repid     = sy-repid                       
      dynnr     = '0100'                         
      side      = go_conteneur->dock_at_bottom   
      extension = 1000                           
      name      = 'CONTENEUR'                    
    EXCEPTIONS                                   
      OTHERS    = 1.                             
  CREATE OBJECT go_controle_html                 
    EXPORTING                                    
      parent = go_conteneur                      
    EXCEPTIONS                                   
      OTHERS = 1.
But when it's shown my ALV disappears!!!
