What is the exact problem with this file?

Question

Hi all,
There is an old form , which was not in use from many days.
Now when we tried to run the form, i got the error saying "FRM-40734:Internal Error:Pl/SQL error occured.", in the login form.
When i tried to open the fmb file in Oracle Forms Builder 6i, i got the following error:
FRM-10102: Cannot attach PL/SQL library d2kwutil. This library attachment will be lost if the module is saved., but the fmb file got open.
The login button has the following code:
DECLARE
  UNAME VARCHAR2(30);
  --USER_ID PARAMLIST;
  V_USER APUSERMA.USER_NAME%TYPE;
  V_PASSWED APUSERMA.USER_PASSWD%TYPE;
BEGIN
select user_CD INTO :GLOBAL.USER_ID from apuserma 
where user_CD = :TI_USER_NAME AND user_PASSWD = :IT_USER_PASSWD
AND SYSDATE BETWEEN USER_VALID_FRM AND USER_VALID_TO;
:global.user_id  := substr(win_api_environment.read_registry('HKEY_LOCAL_MACHINE\system\currentcontrolset\control\computername\computername','computername'),1,10);
:global.compname := :compname;
compnm(:compname);
--USER_ID := CREATE_PARAMETER_LIST('USER_id_NAME');
call_form('Forms\MAIN_SCREEN',hide,DO_REPLACE);
exception
  when no_data_found then
  MESSAGE('Incorrect Username or Password.  Please Re-Enter');
  message(' ');
  RAISE FORM_TRIGGER_FAILURE;
END;
EXIT_FORM;
When i tried to compile, i got error saying ,
Error 201 at line 10, column 28
identifier 'WIN_API_ENVIRONMENT.READ_REGISTRY' must be declared.
I am not getting to know What is the exact problem with this file?
Help me with this please.
Thank You.

I also want to know what is the use of  win_api_environment.read_registry('HKEY_LOCAL_MACHINE\system\currentcontrolset\control\computername\computername','computername') ??
What does it do??
If i comment the following line , will it be a problem??
:global.user_id  := substr(win_api_environment.read_registry('HKEY_LOCAL_MACHINE\system\currentcontrolset\control\computername\computername','computername'),1,10);
Because i commented the above line & compiled, so it is not giving any error now.
So please tell me what win_api_environment.read_registry does??
it's read windows registry value. So, no problem if you comment it.
Thanks
