I think you should be using
plot k=:foo/\.d=:(?200$6) { _1 2 _3 4 _5 6
Remember that 1 foo 2 foo 3 foo 4 is equivalent
to 1 foo (2 foo (3 foo (4))) but that \ works against
prefixes.In other words, you are seeing secondary effects of previous intermediate results having been clamped when you use foo/\ -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
