Subject:      Re: Defining number of elements in an array

Paul,
I think I do not fully understand: what you do not know? how many variables
should be in the variable list, or how must the dimension of the array be?

data a;
  set sashelp.class;
  array test(*) _numeric_;
  x=dim(test); put x=;
run;

as an example. I do not know, how many numerics are in the dataset...
Is that something which you want?
Gerhard
