Narrative:

Aircraft checked on level FL410; he was squawking a wrong code; which I corrected. Other than the wrong code; the data block was correct. The aircraft filed as a slant Q; the data block indicated the aircraft was rvsm capable and I applied rvsm procedures. I was informed by management later that the aircraft was negative rvsm. The pilot was on an international flight and had extensive remarks filed in the flight plan; the last statement in the remarks was 'non rvsm'. Due to character limitations of the right crd and uret; this information is not displayable to the controller or d-side. Pilot filed the wrong suffix code. This would have been discovered sooner if the remark section wasn't so long and the most important information was entered first vice last.
