IS THE "COMMENTED" AND THE "NON SCOMMENTED" LINES DOING THE SAME THING IN THE BELOW CODE????
THANKS
data want;
set ints_exts2;
array ins int:;
array outs ext:;
do i = 1 to dim(ins);
if ins(i)^=. and outs(i)^=. then duration=sum(duration,outs(i)-ins(i)) /*UNCOMMENTED*/
*if 2=N(ins(i),outs(i)) then duration=sum(duration,outs(i)-ins(i)); /*COMMENTED*/
end
;
days = datepart(duration);
time = timepart(duration);
hrs=time/(60*60);
Total_vent_hours =days*24+ time/(60*60);
vent_days=Total_vent_hours/24;
run;
Not exactly as the Not missing, ^=., works for character variables while N(variables) requires all of the arguments to be numeric.
If you are dealing with mixed data types you might want CMISS(ins[i], out[i]) = 0
Thanks Reeza.
INS and OUTS arrays contain dates only. Can have missing values.
Wanted toi know if in that case both line output the same results??
Thanks
You could check with:
compare =(ins(i)^=. and outs(i)^=.) = (N(ins(i),outs(i)));
