Like Bjorn suggests, the OOP lab sounds like what you are looking for (it is in the "Language" group of labs). That said, incrementing things repeatedly in J is usually the wrong approach. Incrementing things repeatedly in J is sort of like using your car to transport objects on to the roof of your house by adding and removing air from the shocks so you can implement a ratchet device. It can certainly be made to work, but if there is an actual problem you are trying to solve, there might be better approaches? -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
