Can I use array to append multiple datasets ?

[Arun_shSAS]

data a1 a2 a3;

input x;

cards;

1

2

3

;

I want a1 a2 a3 to be appended into a single dataset using an array. Please, suggest.

Why not just use a SET statement?

data want ;
  set a1-a3 ;
run;

Using array.

That does not make any sense. The ARRAY statement in SAS is used as a way to make it easy to treat a series of variables as if they formed an array of values.  It has nothing whatsoever to do with datasets.

Your code will produce 3 identical datasets, each containing 3 observations. If you want just one dataset, use

data A;

input x;

cards;

1

2

3

;
