Function DbRList() Foundation
Returns a list of relation names defined for child work areas.
DbRList() --> aRelationNames
The function returns a one dimensional array holding strings in its elements. The strings are the names of relations defined for child work areas. When no relation is defined, the return value is an empty array.
The function is used to determine the names of relations defined for all child work areas of a parent work area. If the function is called without alias operator, the current work area is used as parent work area.
Relation names are similar to alias names of work areas or tag names of indexes. They provide a comfortable way for programming with relations since a symbolic name, rather than an ordinal position, can be used to address a specific relation.
