Return Value
Type: UsualRemarks
For DBServer, this method is used to intercept references to field names as exported variables, which ordinarily would not be allowed. If the field name is valid, it does FieldGet() for the corresponding field name, in effect turning database fields into Access methods of each DBServer object. See "Objects, Classes, and Methods" in the Programmer's Guide for more information on NoIVarGet().
