Representation of Presentation variable

Got a request from OTN forum- https://forums.oracle.com/thread/2562081 asking for the formatting of the presentation variable representation-
User wants to show in the dashboard the exact representation of the presentation variable as below
@{My_PV}{Horse}

Used HTML ascii codes for the same-

1. In the criteria column formula use-

case when 1=1 then '@{Geo_Var1}{AMERICA}' else

dummy_column_name

end

2. In the narrative view, prefix use -@{Geo_Var1}

3. In the narrative section - {@1}

4. Rows to display - 1

There should be another way for this...

Comments are always welcome...
