Question : Oracle Packages

I am trying to understand a stored procedure that uses a package. It just seems to be incrementing and decrementing a variable within the package and not using the value elsewhere that I can find.

I will attach the code for the package and a snippet that uses it:

CREATE OR REPLACE PACKAGE hdb."GLOBALPKG" 
AS
TYPE RCT1 IS REF CURSOR;
TRANCOUNT INTEGER := 0;
IDENTITY INTEGER;
END;
/

and in a stored proc:

CREATE OR REPLACE PROCEDURE       hdb.spDoStuff 
(
	IN_SSN                     IN      	CHAR DEFAULT NULL,
	RCT1                        IN  OUT 	GLOBALPKG.RCT1

)

...
GLOBALPKG.TRANCOUNT := GLOBALPKG.TRANCOUNT - 1;
