Dictionary says: 2!:1 y Spawn. (Unix only.) Like 2!:0, but yields '' without waiting for the host to finish. Any output is ignored. For example, 2!:1 can be used to invoke a text-editor.
But I tested on Linux and Mac, 2!:1 on both still waits for the process to finish. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
