Is there an actual question here?
What is it that you want to do with that dataset?

You want three datasets? Not three variables (one for each class of character)?

It seems we even have to write your questions for you.

Do you mean to have three datasets, each with a character variable x,

where the first contains

abacd

the second

and the third

=@7!*#$ ^

Yes i want create datasets individually as you said

data char digit special;
x='abacd123=@7!*#$ ^';
char=compress(x,,'ak');
digit=compress(x,,'kd');
specialchar=compress(x,,'kp');
run;
i do not know how to keep special characters using compress function

You already have everything you need, you just need to use it "the other way round".

So ask yourself first: "what does the modifier string 'ak' do?"

But that code just creates three duplicates of the same dataset.

If 'ka' keeps alpha and 'kd' keeps digits then to get everything else use 'ad' without the k.
