I am a little bit confused about the following code:
DATA myshortoutputfile;
SET myoutputfile;
casenum = _N_;
IF casenum IN ( 164, 47, 55, 68, 2, 52, 61, 10, 1, 169) EQ 0
THEN DELETE;
RUN;
why do we need EQ 0 and THEN DELETE here? Isn't this code equal to:
data myshortoutputfile;
set myoutputfile;
casenum = _N_;
if casenum IN (164, 47, 55, 68, 2, 52, 61, 10, 1, 169);
run;
Thanks.
