Can you create Static variables within SP ?

I am trying to write a SP that will return me the next first record but I need to have a static variabel to seed my sp.

Any Ideas would vbe greatly apprecieated.

my SP is a s follows : I would like FirstCount to be static

CREATE PROCEDURE DestRackTest @TubeOrder  int  
AS


declare @ret_val nvarchar(50),
             @rackIndex Int,
             @FirstCount  int

SET @rackIndex =@Tubeorder % 96

IF @rackIndex = 1 AND @FirstCount > 0
BEGIN
     SET @FirstCount = @FirstCount + 1
     SET @ret_val = (SELECT Top 1 dbo.FinalDestRack .RackInfoID from dbo.FinalDestRack)
     DELETE FROM FinalDestRack where dbo.FinalDestRack.RackInfoID = @ret_val
     SELECT Top 1 dbo.FinalDestRack.RackInfoID
     FROM  dbo.FinalDestRack
END
 
ELSE
BEGIN
     SELECT Top 1 dbo.FinalDestRack.RackInfoID
     FROM dbo.FinalDestRack
END
GO
