How to show all observations that include special characters

I have one variable in a dataset that include letters, numbers and special characters. Is there way I can screen out observations with ONLY letters, ONLY numbers, and ONLY special characters.

I am presenting some simple code here, You can modify as per your exact requirement!!!

data have;

Input name $;

datalines;

RAVI

1234

HARI

5678

%$#@

;

data want;

set have;

if verify(trim(left(name)),'0123456789')=0 then x = 'N';

else if verify(trim(left(name)),'!@#$%^&*()')=0 then x = 'S';

else x = 'C';

Result :

Obs name x

1 RAVI C

2 1234 N

3 HARI C

4 5678 N

5 % # S

Hello,

One solution below:

data have;
length b $ 7 ;
infile datalines truncover;
input a $200.;

if length(compress(a,,'ad')) gt 1 then b="Special";
else if length(compress(a,,'d')) gt 1 then b="Letters";
else b="Digits";
datalines;
