Question: questions more questions

Hello, I´m trying to create a maplets, but crash out with problem, I don´t now how to create in a smart way a method for count the number of varibles, I did that in the following lines: for Num from 1 to 1E6 do > A[Num]:=assigned(u[Num]): > if A[Num]=true then > N:=Num > end if; > end do: u[k] is a vector, and N, obviously the number of them. because I guess that the user, don´t want introduce more than a million of vectors, I don´t like that way. If somebody know the answer to my (maybe silly) question, please, explain it. Please replace this text with the link to your file. The link can be found in the File Manager
