Package creation/calling package
I made this script but I still don't quite understand if the syntax is correct. I just wanted to create a function and call it in an anonymous block. I then wanted it to use a variable as a parameter in an iteration and output the variable every iteration. It's done basically but I know it's not 100% right. The fibonacci function looks like its going to loop an infinite number of times if the parameter is greater than 2.
CREATE OR REPLACE PACKAGE myPACKAGE AS
CREATE OR REPLACE FUNCTION fibonacci
(n BINARY_DOUBLE) RETURN BINARY_DOUBLE IS
IF n <= 2 THEN
RETURN fibonacci(n-2) + fibonacci(n-1);
DBMS_OUT.PUT_LINE('Enter an integer: ');
numbere := &input;
IF numbere < 30
counter := 5;
counter := 10;
FOR i IN..counter LOOP
numbere := fibonacci(numbere)
DBMS_OUT.PUT_LINE(i || ': ' || numbere || '***')
DBMS_OUT.PUT_LINE('Final value: ' || numbere);

Perhaps you could learn all about packages, procedures and functions if you Read This Fine Manual:

The manual is horrible. I'm also using PL/SQL Programming written by Oracle. Well, I'm going to assume that it's correct since nobody is posting or that nobody on this forum knows about PL/SQL.

I use oracle doc, java doc by oracle, PL/SQL manual by oracle.
Keep your snide comments to yourself. I don't understand a lot of the syntax of PL/SQL and I work with over 7 languages. So, please help me or do not post discouraging comments. All I want to know is ANYTHING WRONG WITH THE SCRIPT THAT "I" WROTE. SO OBVIOUSLY I UNDESTAND SOME THINGS....THANK YOU.

Second of all, all of the code you see, I had to use java doc and pl/sql programming by oracle TO CREATE.
AND THIRD OF ALL WHEN I CAME TO THIS FORUM I TYPED PL/SQL AND HELP INTO GOOGLE...OKAY SO TAKE THE WORD HELP OUT OF YOUR SEARCH WORDS.

Obviously you don't understand anything and it seems you did not even consult the manual to be able to code using the CORRECT syntax:
