YourQuery.CaluclatedFields.Add( "CODIGO Integer" );

My Delphi IDE don't display YourQuery.CaluclatedFields.xxxxxx. why?
My ibo version is 4.2.Ie.

CaluclatedFields is new in more recent versions?

In relation to "Your variable names are *far* too long" I reduce the name.
Now
QpcPronto.FieldDefs.Add('CODIGO', FTinteger,0,true);
but problem persist at QpcProntoCODIGO.OnGetText:=QpcProntoCODIGOgettext;
