That's my personal take on it. Please keep in mind, that I, like you, am
only a member of the community, and not a OMI-employee.

Why would you want to do this?

If you use the fully qualified variable throughout your programs, you
possibly have less work typing the names, but you definitely have a higher
grade of readability in your code.

As far as I understand the concept of CP, I would strongly discourage
assigning imported variable A to local variable B, in order to save typing
time only. And if there is a very good reason beyond mere saving typing
time, this reason would also suggest that you export the additional
variable.

Besides that, I do not think that the case you make above is really a case
at all. IN your above example, the table apparently is:

<SubsytemModule>.rt.base

So your database pointer, if you exported one, would be:

<SubsytemModule>.db

and if you wanted to assign it to local variable db (for whatever reason),
you would have to type

db:= <SubsytemModule>.db;

instead of

db:=<SubsytemModule>.rt.base;

So, we are talking about an additional of 4 characters that you call "also a
bit redundant"? I don't think that this is an issue.

Rene
