Need to turn this PLSQL into a procedure

Question

Hi All,
I have the following PLSQL which declares a cursor, then loops using the cursor variable. I'm new to creating procedures and packages and i'm having trouble turning this PLSQL into one of those. When i put my PLSQL code in a procedure it doesn't like the DECLARE statement or the CURSOR section. I'm not sure how to tweak it to get the syntax correct for a procedure. Can someone point me in the right direction?
Here is the PLSQL:
DECLARE
/* Output variables to hold the result of the query: */
groupid assignment_group.id%TYPE;
/* Cursor declaration: */
CURSOR Asset_Rank_HistoryCursor IS
select distinct id from assignment_group;
BEGIN
OPEN Asset_Rank_HistoryCursor;
LOOP
/* Retrieve each row of the result of the above query into PL/SQL variables: */
FETCH Asset_Rank_HistoryCursor INTO groupid;
/* If there are no more rows to fetch, exit the loop: */
EXIT WHEN Asset_Rank_HistoryCursor%NOTFOUND;
/* Insert the the new rows */
insert into ASSET_RANK_GROUPED (asset_id , dt, rank, score, ASSIGNMENT_GROUP_ID)
select asset_id, max_dt, rownum, score, groupid from (
SELECT <big nasty select statement>
END LOOP;
/* Free cursor used by the query. */
CLOSE Asset_Rank_HistoryCursor;
END;
How do i change my DECLARE and CURSOR statement so the procedure will create. Do i need to break it out into a function?

Answer 1

I figured it out... just had to play w/ the syntax. Had to make sure the BEGIN statement was AFTER the CURSOR declaration and had to make sure any variables are declared up top, didn't need a DECLARE section in procedure. I just put the groupid variable right after IS at the top of procedure creation statement.
