Note that in the general case, !. is not suitable for specifying fill. This is because !. is not supported on arbitrary verbs created using the rank operator. In the general case, you can specify fill for numeric arrays using addition. In the general case, you can specify fill for character arrays by mapping them as numeric arrays. In the general case, it's probably not a good idea to use anything but the default as fill for boxed arrays. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
