0 NUMBER OF RECORDS IN TABLE=       14  LINES=      9 

I think &RECORDS is the variable the contains the number of records the request retrieved.  

&LINES is the variable that contains the number of lines in the answer set.

TABLE FILE CAR
SUM RCOST BY COUNTRY
END

will give you different LINES from
TABLE FILE CAR
PRINT RCOST BY COUNTRY
END

Same number retrieved but different number in the output.

  
TABLE FILE ORDER_PAYMENTS
BY ORDER_KEY AS 'ORDER_NUMBER'
BY CUST_ID AS 'CUST_NUMBER'
WHERE ORDER_DT GE HADD((HGETC(8, 'HYYMDs')), 'DAY', -30, 8, 'HYYMDs');
WHERE INACTIVE_ACCT NE '1' OR INACTIVE_ACCT EQ MISSING;
WHERE ORDER_KEY IN &ORDER_KEY;
ON TABLE SET ASNAMES ON
ON TABLE HOLD AS CUST_ORDERS FORMAT FOCUS INDEX ORDER_KEY
