Hiding the code

Question

Hi All,
Can anyone tell me how to hide the code of a report from the user? I know that if I goto the program's attributes and change its STATUS to SYSTEM PROGRAM, it cannot be debugged, but I have been told that tweaking the debugger will still allow me to debug the application.
Please help,
Regards,
Madhur

Hi,
Pl find the sample program.
Hiding ABAP Source code
PROGRAM ZHIDE NO STANDARD PAGE HEADING.
This program hides any ABAP's source code and protects it with a
password in this source code.  So the first candidate to be hidden
should be ZHIDE itself.
After hiding, you can still run the abap (the load version is intact)
but it cannot be displayed, edited, traced, transported or generated.
If the ABAP is not hidden, the program hides it, if it is hidden, it
unhides it.
To execute this program, change the user name and password in this
source code first.
SELECTION-SCREEN BEGIN OF BLOCK BLOCK.
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN COMMENT 1(8) PWD.
SELECTION-SCREEN POSITION 35.
PARAMETERS: PASSWORD(8) MODIF ID AAA.
SELECTION-SCREEN END OF LINE.
PARAMETERS: PROGRAM(8).
SELECTION-SCREEN END OF BLOCK BLOCK.
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF SCREEN-GROUP1 = 'AAA'.
      SCREEN-INVISIBLE = '1'.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.
INITIALIZATION.
  PWD = 'PASSWORD'.
START-OF-SELECTION.
  TABLES: TRDIR.
User name and passsword check
  IF SY-UNAME <> 'SAP' OR PASSWORD <> 'PASSWORD'.
    WRITE: / 'Wrong password'.
    EXIT.
  ENDIF.
SAP owned?
  IF NOT PROGRAM CP 'Z' AND NOT PROGRAM CP 'Y'.
    WRITE: / 'Do not hide original SAP programs!'.
    EXIT.
  ENDIF.
Exists?
  SELECT SINGLE * FROM TRDIR WHERE NAME = PROGRAM.
  IF SY-SUBRC <> 0.
    WRITE: / 'Program does not exists!'.
    EXIT.
  ENDIF.
Does it have a current generated version?
  DATA: F1 TYPE D, F3 TYPE D.
  DATA: F2 TYPE T, F4 TYPE T.
  EXEC SQL.
  SELECT UDAT, UTIME, SDAT, STIME INTO :F1, :F2, :F3, :F4 FROM D010LINF
                       WHERE PROG = :PROGRAM
  ENDEXEC.
  IF F1 < F3 OR ( F1 = F3 AND F2 < F4 ).
    WRITE: / 'The program has no recent generated version!'.
    EXIT.
  ENDIF.
Compose a new program name
  DATA: NEW_NAME(8), I TYPE I, J TYPE I.
  NEW_NAME = PROGRAM.
  DO 8 TIMES.
    I = SY-INDEX - 1.
    NEW_NAME+I(1) = '_'.
Search for acceptable program name variations
    J = 0.
    SELECT * FROM TRDIR WHERE NAME LIKE NEW_NAME.
      J = J + 1.
    ENDSELECT.
    IF J = 1.
      EXIT.
    ENDIF.
    NEW_NAME = PROGRAM.
  ENDDO.
Cannot generate appropriate program name
  IF J > 1.
    WRITE: / 'Cannot generate appropriate program name'.
    EXIT.
  ENDIF.
Check if it is already in d010s (already hidden)
  DATA: F5(8).
  EXEC SQL.
    SELECT PROG INTO :F5 FROM D010S WHERE PROG = :NEW_NAME
  ENDEXEC.
  IF F5 IS INITIAL.
There is no such hidden program, hide it
    EXEC SQL.
      UPDATE D010S SET PROG = :NEW_NAME WHERE PROG = :PROGRAM
    ENDEXEC.
  ELSE.
There is already a hidden program there, unhide it
    EXEC SQL.
      UPDATE D010S SET PROG = :PROGRAM WHERE PROG = :NEW_NAME
    ENDEXEC.
  ENDIF.
end of program
