Macro substitution generally needs a Dot - but, the 2nd dot represents
the dot you normally use between the Table name and the Field. Thus 2
dots! Make sense???

Ted and Gianni,
I'm not familiar with the double dots you both used. When is this

Why not macro substitution?

Note that the two dots are mandatory.
In many cases it is better to use macros because they are expanded and
interpreted only one time.
For example in sql query, in filter condition, in for clauses.
