E2018 Record, object or class type required (Delphi)
Go Up to Error and Warning Messages (Delphi)
The compiler was expecting to find the type name which specified a record, object or class but did not find one.
program Produce; type RecordDesc = class ch : Char; end; var pCh : PChar; r : RecordDesc; procedure A; begin pCh.ch := 'A'; (* case 1 *) with pCh do begin (* case 2 *) end; end; end.
There are two causes for the same error in this program. The first is the application of '.' to a object that is not a record. The second case is the use of a variable which is of the wrong type in a WITH statement.
program Solve; type RecordDesc = class ch : Char; end; var r : RecordDesc; procedure A; begin r.ch := 'A'; (* case 1 *) with r do begin (* case 2 *) end; end; end.
The easy solution to this error is to always make sure that the '.' and WITH are both applied only to records, objects or class variables.
