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