Hi,

I’ve created Array with NullableInteger as Element Type  
My generated \_Intf.pas has code (RO ver 10.0.0.1613):  
`function NullableIntegerArray.IndexOf(const aValue: NullableInteger; const aStartFrom: Integer = 0): Integer;`  
`var`  
` lResult: Integer;`  
`begin`  
` for lResult := aStartFrom to fCount - 1 do`  
` if fItems[lResult] = aValue then begin`  
` Exit(lResult);`  
` end;`  
` Exit(-1);`  
`end;`  
Compiling error for `fItems[lResult] = aValue`:  
`[dcc32 Error] E2015 Operator not applicable to this operand type`

Is it possible add to Nullable Records in uRONullable additional operator `Equal`  
`class operator Equal(const a, b: NullableInteger): Boolean;`

Hi,

as a workaround, you can generate \_Intf.pas with with `GenericArray` = `Auto`:
