Package procedures can't call builtin's?

I'm writing my first stored package in Oracle 7 and am getting the following messages:

39/11    PLS-00313: 'MESSAGE' not declared in this scope      
39/11    PL/SQL: Statement ignored                            
40/11    PLS-00313: 'BELL' not declared in this scope         
40/11    PL/SQL: Statement ignored                            
42/15    PLS-00201: identifier 'ERROR_CODE' must be declared  

The code segment causing this is:


        /* Check for error messages */                           


        ELSIF -3000 < msg_num and msg_num < -1999 THEN           
          MESSAGE('E'||TO_CHAR(msg_num)||': '||app_msg);         
          BELL;                                                  
                                                                 


        /* Assume all others are system messages */              


                                                                 
        ELSIF ERROR_CODE = 0 THEN   /* Message type */           
          MESSAGE(MESSAGE_TYPE||' '||TO_CHAR(msg_num)||': '||    
                  MESSAGE_TEXT);                                 

The procedure works fine when embedded in a SQLFORMS 3.0 form. Aren't SQLFORMS built-in functions automatically available in SQLPlus?
