DBRELATION()

    DBRELATION() determines the linking expression of a specified relation
    in the current work area.

Syntax

    DBRELATION(<expN>)

Argument

    <expN> is the ordinal position in the list of relations defined.

Returns

    A character string.

    DBRELATION() returns a character string containing the relation
    expression of the relation pointed to by <expN>.  If there is no
    RELATION SET for <expN>, DBRELATION() returns a null string ("").

Usage

    DBRELATION() is used in combination with DBRSELECT() to query the
    linking expression and work area of an existing relation.  Using these
    functions in addition to DBFILTER(), you can create a user-defined View
    system analagous to that of dBASE III PLUS and the Clipper utility,
    DBU.EXE.  Essentially, you utilize these functions to create the View
    definition from the environment.
