how to separate names into 2 parts?

Question

I have a name list:

input nms $28. ;
 cards;
Abcd Efgxxeg, BSN, RN
Dudng Nioll, RN, CCM
Doujh Keeloou, RN
Hardlop Aceed RN BSN
Jnmjkl Tuutt, BSN  RN, CCM

;
run;

and I want split the first name and rest of the names w/o any change into 2 colums, first_nm and last_nm:

 first_nm  last_nm
 Abcd      Efgxxeg, BSN, RN
 Dudng     Nioll, RN, CCM
 Doujh     Keeloou, RN
 Hardlop   Aceed RN BSN
 Jnmjkl    Tuutt, BSN  RN, CCM
 Kommmbbey Maxxt, RN, CM

Answer 1

data want;
   set nurse_0;
   first_nm = scan(nms, 1);
   last_nm = substr(nms, find(nms, ' ') + 1);
   drop nms;
run;

Result:

first_nm   last_nm
Abcd       Efgxxeg, BSN, RN
Dudng      Nioll, RN, CCM
Doujh      Keeloou, RN
Hardlop    Aceed RN BSN
