(`(<;:'u v'))(`a)(`b) |domain error c=:(`(<;:'u v'))(`a)(`b) d c +-+-----+-+-+ |d|+-+-+|a|b| | ||u|v|| | | | |+-+-+| | | +-+-----+-+-+ I stumbled across this while constructing gerunds for verbs to manipulate. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
