is the correct format.
The (T) indicates a conversational text event and there is no equivalent in the DynaPath G Code programming.
DynaPaths use the old RS-274D standard, which never defined comments. Comments can only be entered in Text events (event type T). Editing on the control will limit the length to 16 characters - the length of the input buffer. On the other hand, programs prepared offline are not restricted to 16 characters. Technically they can go up to 255 characters and they should load from offline just fine.
