Description

Provides access to either a list of field names or an index expression.

FieldExpression provides access to the private data member on TIndexDef which contains either a list of field names or an index expression. This data member is used to return the value for the Fields property or the Expression property depending on whether ixExpression is in Options.

This property is only used in the Windows product, where there are components that can represent dBASE tables. This property is used by TBDEDataSet but normally dDevelopers should use the Fields or Expression properties instead.
