Macro in Solidworks Drawing

Hello everyone,
I am self-studying macro programming on SOLIDWORKS using the record tool
I have recorded the dimensioning operation on the drawing and obtained a piece of Code as below:

" Dim swApp As Object

Dim Part As Object
Dim boolstatus As Boolean
Dim longstatus As Long, longwarnings As Long

Sub main()

Set swApp = Application.SldWorks

Set Part = swApp.ActiveDoc
boolstatus = Part.ActivateView("Drawing View1")
boolstatus = Part.Extension.SelectByRay(6.51311660777385E-02, 0.18436038869258, 1.26999999999953E-02, 0, 0, -1, 1.21318727915194E-03, 1, False, 0, 0)
boolstatus = Part.Extension.SelectByRay(0.242470600706714, 0.167589858657244, 1.26999999999953E-02, 0, 0, -1, 1.21318727915194E-03, 1, True, 0, 0)
Dim myDisplayDim As Object
Set myDisplayDim = Part.AddDimension2(0.15041109540636, 0.228957985865724, 0)
Part.ClearSelection2 True
boolstatus = Part.ActivateView("Drawing View3")
boolstatus = Part.ActivateView("Drawing View1")
boolstatus = Part.Extension.SelectByRay(0.127574628975265, 9.26577031802121E-02, 1.26999999999953E-02, 0, 0, -1, 1.21318727915194E-03, 1, False, 0, 0)
boolstatus = Part.Extension.SelectByRay(0.115799575971731, 0.218971908127208, 1.26999999999953E-02, 0, 0, -1, 1.21318727915194E-03, 1, True, 0, 0)
Set myDisplayDim = Part.AddDimension2(5.57929328621907E-02, 0.152246607773851, 0)
Part.ClearSelection2 True
boolstatus = Part.ActivateView("Drawing View2")
boolstatus = Part.Extension.SelectByRay(0.303843604240283, 0.128339681978799, 8.89000000000237E-02, 0, 0, -1, 1.21318727915194E-03, 1, False, 0, 0)
boolstatus = Part.Extension.SelectByRay(0.329177809187279, 0.128339681978799, 8.89000000000237E-02, 0, 0, -1, 1.21318727915194E-03, 1, True, 0, 0)
Set myDisplayDim = Part.AddDimension2(0.316689116607774, 7.59579858657241E-02, 0)
Part.ClearSelection2 True
boolstatus = Part.ActivateSheet("Sheet1")
End Sub"

I am not understanding how to link the data type  boolstatus = Part.Extension.SelectByRay(6.51311660777385E-02, 0.18436038869258, 1.26999999999953E-02, 0, 0, -1, 1.21318727915194E-03, 1, False, 0, 0), what do the characters inside the brackets mean

can anyone explain to me what these lines of characters mean. Thanks a lot
