Hi - I have also experienced this problem. What I do to get around it is to break up the computation into two steps, as follows: let B=A[k=@max] let C=A[l=@max]. This solution may not be satifactory to you, but it may help for the time being. - Jeremy On Thu, 22 Oct 1998, Donald S. Dunbar wrote: [NON-Text Body part not included]
