VB 6.0 - How to exit from nested subroutines in VBScript

I have subA, subB, subC these 3 subroutines.
subA have call to subB and subB have call to subC and for any condition, if i want to get out of SubA directly from SubC then How I can do this?

in Vb Script use Exit Sub to come out of a routine


eg

Sub CreateUser(strVar1, strVar2, strVar3, strVar4)
' Process values from recordset.
If (strVar1 = "") Then
' Necessary condition not met.
Exit Sub
End If
' More processing.
End Sub
