Printing some data from table: KNA1 in SAP..

..

Here is my code:
REPORT ZTMP_TEST.
 
DATA: BEGIN OF CUST_STRU,
 KUNNR LIKE KNA1-KUNNR,
 NAME1 LIKE KNA1-NAME1,
 ORT01 LIKE KNA1-ORT01,
 PSTLZ LIKE KNA1-PSTLZ,
 STRAS LIKE KNA1-STRAS,
END OF CUST_STRU.
 
SELECT KUNNR NAME1 ORT01 PSTLZ STRAS FROM KNA1 INTO CUST_STRU.
 WRITE: /1(2) SY-DBCNT, 4(10) CUST_STRU-KUNNR USING NO EDIT MASK,
     15(35) CUST_STRU-NAME1, 51(35) CUST_STRU-ORT01, 
     87(10) CUST_STRU-PSTLZ, 98(35) CUST_STRU-STRAS. 
ENDSELECT.

And the output will be:
