Is there an API in Demantra translates the exp_template field from the computed_fields table into PL

I have a customer who wishes to copy a series into a table in a database.  They wish to copy the series even if the underlying server expression changes for that series.

They don't like the idea of an export.

So all i can think of is to turn the exp_template value for the series from the computed_fields table into PL/SQL.

Is there an API that exists for this?  It seems Demantra does this internally.  How can I do this without writing an interpreter for the psuedo-code in the exp_template field myself?

Any help would be appreciated.
