This function should be used to create a new label. The label can be named or unnamed. Note that this structure does NOT contain the name of the label.
pSymbolLABEL _new_SymbolLABEL(peXobject pEx
Also note that all labels are global in a basic program and are subject to name space decoration. However the same named label can not be used in two different functions in the same name space.
A label has a serial value, which is not actually used and a number of the node that it points to.
