The dyadic system function Name Description Type Code 'F' for function 'N' for a numeric array 'C' for a character array Name Name of the object, followed by a blank Rank Character form of the rank of the object Shape Character form of the shape of the object followed by a blank Data Character form of the object The standard transfer form cannot be used for mixed or nested variables or for userdefined operators. The extended transfer form is a character string which, if executed, would reconstitute the item in question.
