Indirect addressing using VBS

Hi!!

I'm working with WinCC V6.2 & i'msome what newuser to VBS.
I've made a tag as text tag(internal tag)& i'm attaching the text tag to i/o field output in screenby selecting indirect addressing so that whatever actualname of tag(externaltag)i passed in it,so thati get the value ati/o field.

i.e. "Temp" - Text Tag 8-Bit(internal) = Actual tag at connection.

This thing i'm achiving well directly using WinCC indrect addressing concept,but how to do it using VBS as i want to "Xor"my actual tag value to get togglebit or something else.
Can anybody help me out.

Thanks & Regards,

Function SetAddress(Tagname,Address)
	Dim HG, strVariableName
	Set HG = CreateObject("HMIGenObjects.HMIGO")
	HG.GetTag Tagname
	HG.TagS7S5Address = Address
	HG.CommitTag
	Set HG = Nothing
End Function
