ORA-00922 error when user calls sys.verify_function from forms

Question

Hi there,
I have a form to change the user's current password.
After user provides new password and clicks on OK button, it calls a database procedure called "change_pwd" which calls the Alter command.
I modified the SYS.verify_function, which has the code
-- rule Passwords can only contain A-Z, 0-9, _
   violate_rule_five := FALSE;
   FOR v_char IN 1 .. lv_pwd_len
   LOOP
      v_this_char := UPPER (SUBSTR (PASSWORD, v_char, 1));
      IF (   ((v_this_char >= 'A') AND (v_this_char <= 'Z'))
          OR ((v_this_char >= '0') AND (v_this_char <= '9'))
          OR (v_this_char = '_')
      THEN
         violate_rule_five := FALSE;
      ELSE
         violate_rule_five := TRUE;
         GOTO violrule5;
      END IF;
   END LOOP;
   <<violrule5>>
   IF violate_rule_five = TRUE
   THEN
            raise_application_error (-20600, lv_error_msg);
   END IF;When i try to change the password to 'blah-blah1' i expect it to show be error 20600. But instead shows ORA-00922.
Why is this happening?
All other rules in the verify_function are working correctly.
Please help.
I added the [ code ] tags to make the code easier to read.

I have noticed just now that a dump file having a name like ifrun60_dump_299, is generated by FORMS every time I issue the aborted call to the foreign function.
Inside the form dump file, apart from useless info like Registers and so on, the message:
"Could not find Module32First"
By a FILE/FIND/CONTAINING TEXT I searched all the DLLs, and I noticed that Module32First is a routine that can be found within each of the following DLLs:
Cl32
d2kwut32
d2kwut60
I tried to load those DLLs along with SECURSIGN.DLL by modifying the PROCEDURE LoadLibrary into the FFI-generated PLL code, and I have apparently no problem in loading all the DLLs that I wish, but the error persists, and that dump file is constantly generated, always looking for the "Module32First" routine.
How can I avoid all that mess and the FRM-40734 error??
