Hi Fabio,

There's no single command that will tell you that but you can use following UDF

*FUNCTION IsPropertyHidden
LPARAMETERS toObject, tcPropertyName 
RETURN PEMSTATUS(toObject, tcPropertyName,5) ;
		AND NOT PEMSTATUS(toObject, tcPropertyName,2) ;
		AND TYPE([GETPEM(toObject, "] + tcPropertyName + [")]) = "U"
