Executing functions in sequence defined in a package - oracle

Question

I've been given the task of converting a stored procedure, with several CRUD operations, to a package with functions defined.
When I created the package in Oracle SQL Developer, I defined may functions:
FUNCTION func1 RETURN NUMBER;
FUNCTION func2 RETURN NUMBER;
etc...
I have corresponding code in the 'package body':
FUNCTION func1 RETURN NUMBER
IS
BEGIN
-- some CRUD operation
END;
RETURN 0;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line('FUNCTION func1: error ' || ERR_NUM || ', Msg:' || ERR_MSG);
ROLLBACK;
END func1;
When I run them, I can choose which function to run from the list supplied. My question is what do I need to write or do to have all functions run in sequence with one command?
thanks

If you need to run some procedures in a given order, you need to build a procedure or an anonymous block that calls the procedures in the right order.
For example:
create or replace package aPackage is
procedure runAll;
end;
create or replace package body aPackage is
procedure proc1 is
begin
dbms_output.put_line('Procedure 1');
end proc1;
--
procedure proc2 is
begin
dbms_output.put_line('Procedure 2');
end proc2;
procedure runAll is
begin
proc1;
--
proc2;
--
end runAll;
end;
The call:
SQL> exec aPackage.runAll;
Procedure 1
Procedure 2
PL/SQL procedure successfully completed.
SQL>
I used procedures just to call them without need to assign the result to a variable, but the idea is the same for functions.
With functions:
create or replace package aPackageFun is
function runAll return number;
end;
create or replace package body aPackageFun is
function fun1 return number is
begin
dbms_output.put_line('Inside function 1');
return 1;
end fun1;
--
function fun2 return number is
begin
dbms_output.put_line('Inside function 2');
return 2;
end fun2;
function runAll return number is
vNum1 number;
vNum2 number;
begin
vNum1 := fun1();
--
vNum2 := fun2();
--
return vNum1 + vNum2;
end runAll;
end;
The call:
SQL> select aPackageFun.runAll() from dual;
APACKAGEFUN.RUNALL()
--------------------

Inside function 1
Inside function 2

About your code, notice that you have a commit after a return: the commit will never be executed.
