DBRSELECT(), SET RELATION

Description

The TARGET() function is synonymous with the DBRSELECT() function. The TARGET() function returns the target workarea of a specified relation defined in the current workarea. By default, the Recital environment supports 20 workareas but this can be increased, by setting the environment symbol DB_MAXWKA to a higher value, which allows for up to (DB_MAXWKA-1) relationships. The <expN> is the position of the corresponding relation in the list of previously defined relations. If there are no relations defined for the <expN> on the currently selected table, the TARGET() function will return 0.

Example

use shows in 2 index people
