SQL & PL/SQL :: Unable To Create DB Package?

I´m having a trouble creating a db package. I´ve changed my job and now i´m working full on DB instead of Forms Developer.

So my trouble is that i want to create some like a global cursor on DB package, i know you can create global variables and use it on all the procedures/function inside the package. But how about cursors?

My problem: I dont´know how to declare into the spec. I don´t know how to use it on body.

My actual

I have the structure below:

PackageSpec:
CREATE OR REPLACE PACKAGE [i]MyPackageName[/i]
IS
CURSOR [i]myGlobalCursor[/i](par1 IN VARCHAR2, par2 IN DATE)(
);
PROCEDURE [i]MyProcedure1[/i](par1 IN VARCHAR2, par2 VARCHAR2);

[code]....
