Newbie: What is Oracle Version of T-SQL stored procedure?

Question

How do I achieve this in PS/SQL? I find that Oracle is worlds more difficult than SQL Server/T-SQL? I simply want to design a package and package body that returns a record for each cash register in a store. containing Week-to-date sales, year-to-date for lLast Year, and YTDSales for CurrentYear. These last 2 values should be returned as a table from a function: Here is the pseudocode'ish: I think I will be able to use this as a template for most of the PL/SQL I have to design:
CREATE PROCEDURE spGetWTDandYTDSales
(@drawerid as integer,
     @startDate as timestamp,
     @endDate as timestamp,
@recordsetOfAmounts Values output)
BEGIN
select fncWTDSales ((@drawerid, @startdate, @enddate) as wtdAmount,           
fncYTDSales(@drawerid, @startdate, @enddate) as YTDAmount1
fncYTDSalesLY(fncYTDSales(@drawerid, @startdate, @enddate) as YTDAmount2
return @recordsetOfAmounts
END ;
CREATE FUNCTION fncWTDSales(@drawerid, @startdate, @enddate)
as money
BEGIN select amount from CashDrawer where drawerid = @drawerid and start_date between @startDate and @enddate
return amount;
END
CREATE FUNCTION fncYTDSales(@drawerid, @startdate, @enddate)
as table
BEGIN
select ytdsales as ytdsales, ytdSalesLY as ytdSalesLY
from CashHistory
where drawerid = @drawerid
from CashDrawer
where drawerid = @drawerid and start_date between @startDate and @end_date
return ytdsales, ytdSalesLY;
END
Clear as mud? Also since several procedures and functions within the package will use the drawerid, startdate and enddate variables, how can i make these global to the package (and/or should I) so i don't have to define as parameters to procedures or functions.
Thanks

You guys are great. Justin's was the clearest answer. How do I givepoints? Here is some background and hopefully my last question:
How do I get rid of the function since a bad idea? (I HOPE I didn't leave anything out)
Background
I came into a job where there was a reporting software package going against an oracle database of generic fields. The company has a CSV table of how these fields are mapped. The reports are written in VB6 code with DLLs and the like. The reports are written like: For each of the 19 fields on report, make a database call via a Simple select statement to get the data. There are no indexes. I copy/pasted the DDL from Oracle Ent. Mgr. to Word Document, it is 4 pages. I’m not making any of this up.
I’ve done a replace on the field names so as to not identity the software package but here’s some of the structures used to solve my problem.:
CREATE  TABLE  SALESTABLE,
                BusinessDate  DATE  NOT  NULL,
                StoreId,
                FIELD8 ,
                FIELD53,
                FIELD54
SELECT  StoreId as store,
            SUM(field8) AS WTDALLSALES,
     SUM(field53) AS WTDCARS,
     SUM(field54) AS WTDSECONDS,
     MYSTORE.GetGuestCount(221, '01-MAY-2008', '08-MAY-2008') AS WTDGuestCount,
               MYSTORE.GetGuestCount(221, '01-MAY-2007', '08-MAY-2007') AS WTDGuestCountLY,
               MYSTORE.GetGuestCount(221, '01-JAN-2008', '01-MAY-2008') AS YTDGuestCount,
               MYSTORE.GetGuestCount(221, '01-JAN-2007', '08-MAY-2007') as YTDGuestCountLY
FROM MYSTORE.SALESTABLE
WHERE StoreId in (243,321,251,363,501)
     AND BusinessDate between '01-MAY-2008' and '25-MAY-2008'
GROUP BY StoreIdMY GUESTCOUNT FUNCTIONCREATE OR REPLACE  FUNCTION  GETGUESTCOUNT
         storeid               IN number,
     startDate          IN date,
     endDate          IN date)
return number
AS
     guestCount     number;
BEGIN
     SELECT SUM(Field82  + Field83 + field84)
     INTO GuestCount
     from MYSTORE.SALESTABLE     where StoreId= storeid
        and  BusinessDate between startdate and enddate;
    return guestcount;
END GETGUESTCOUNT;Here is a portion of the vendor's DDL for the Sales Tables (just to show how confusing name is) which I have cleaned up for this post: (My company has a table of what these fields map to. )
