F2092 Program or unit '%s' recursively uses itself (Delphi)

Go Up to Error and Warning Messages (Delphi)

An attempt has been made for a unit to use itself.

unit Produce;
interface
  uses Produce;
implementation

begin
end.

In the above example, the uses clause specifies the same unit, which causes the compiler to emit an error message.

unit Solve;
interface
implementation

begin
end.

The only solution to this problem is to remove the offending uses clause.
