Labelling an event

[David McFarlane]

If you control everything with a Lists, then you might just add 
a  column (i.e., attribute) to the Lists with the information you 
need.  E.g., a column labeled "Phase" with values of "acquisition" or 
"reversal".

If you control things with inline script, then you may add an 
attribute using the c.SetAttrib method.  E.g.,
     c.SetAttrib "Phase", "acquisition"
Please see the Context.GetAttrib topic in the E-Basic online help.
