Read Access Violation error message

Hi,

 

I tried to construct lagged variables from t-1 to t-5 and had the following error message. The SAS version is 9.3 (TS1M2) and Window 7 with 64 bit OS is installed on my PC. Thanks for your help

 

27 data s3; set s2;

28 lag_txpd = lag(txpd);

29 if gvkey ne lag(gvkey) then lag_txpd = .;

30 lag2_txpd = lag2(txpd);

31 if gvkey ne lag2(gvkey) then lag2_txpd = .;

32 lag3_txpd = lag3(txpd);

33 if gvkey ne lag3(gvkey) then lag3_txpd = .;

34 lag4_txpd = lag4(txpd);

35 if gvkey ne lag4(gvkey) then lag4_txpd = .;

36 lag5_txpd = lag5(txpd);

37 if gvkey ne lag5(gvkey) then lag5_txpd = .; run;

Re: Read Access Violation error message

Have tried using a subset of S2 such as just 5 or 10 records? Does it generate the same error?

 

What does a Proc Contents show for S2?

Re: Read Access Violation error message

Does it always happen? Sometimes it's just a temporary access issue, file being scanned by virus checker or temporary network unavailability. Retry and let us know.

Yes. The same error message comes out. 77 data s3; set s2; 78 lag_txpd = lag(txpd); 79 if gvkey ne lag(gvkey) then lag_txpd = .; 80 lag2_txpd = lag2(txpd); 81 if gvkey ne lag2(gvkey) then lag2_txpd = .; 82 lag3_txpd = lag3(txpd); 83 if gvkey ne lag3(gvkey) then lag3_txpd = .; 84 lag4_txpd = lag4(txpd); 85 if gvkey ne lag4(gvkey) then lag4_txpd = .; 86 lag5_txpd = lag5(txpd); 87 if gvkey ne lag5(gvkey) then lag5_txpd = .; run; ERROR: An exception has been encountered.
