Here is the sample code that will help you calling a function from a procedure.

    create or replace FUNCTION ADD_TEN(P_IN VARCHAR2) RETURN VARCHAR2
    AS
    L_RESULT VARCHAR2(4000);
    BEGIN
    L_RESULT:=P_IN+10;
    RETURN L_RESULT;
    END;



    create or replace PROCEDURE CALL_FUNCTON(P_IN VARCHAR2)
        AS
        L_FINAL_RESULT VARCHAR2(4000);
        BEGIN
        L_FINAL_RESULT:=ADD_TEN(P_IN);
        DBMS_OUTPUT.PUT_LINE(L_FINAL_RESULT);
        -- USE L_FINAL_RESULT IN YOUR BUSINESS LOGIC
        END;

EXECUTE CALL_FUNCTON(5);
