If you want the left arg to be a boolean verb, you have two possibilities: 1) use an adverb 2) require that the left arg be the gerund of the boolean verb. For an english example: if the boolean verb were "choose" the gerund would be "choosing" and we could form sentences where we talk of choosing, or we could have words which modify "choose". J's grammar follow similar constraints. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
