Function to return the target workarea of a relation
The DBRSELECT() function is synonymous with the TARGET() function. The DBRSELECT() function returns the numeric target workarea of a specified relation defined in the current workarea. The <expN> is the position of the corresponding relation in the list of previously defined relations. If there is no relation defined that matches the <expN> on the active table the DBRSELECT() function will return 0.
