The Location table is open as a RecordRef Data Type object and the reference is stored in the LocationRecref variable. The FieldIndex variable that stores the field index is initialized to 0. The LocationRecref variable uses the FieldIndex Method (RecordRef) to create a FieldRef that is named MyFieldRef for the specified field index. MyFiledRef now references the field that is specified by the FieldIndex. MyFieldref is then used to display the number and caption of the field The Number Method (FieldRef) method retrieves the field number. This is repeated for the first ten fields in the table.
var
MyFieldRef: FieldRef;
LocationRecref: RecordRef;
FieldIndex: Integer;
begin
LocationRecref.Open(DATABASE::Location);
FieldIndex := 0;
repeat
FieldIndex := FieldIndex + 1;
MyFieldRef := LocationRecref.FieldIndex(FieldIndex);
Message('Field Number: %1 Field Caption: %2.' , MyFieldRef.Number, MyFieldRef.Caption);
until FieldIndex = 10;
end;
