Do-loop question

pchen002 — Wed, 27 Sep 2017 06:48:17 GMT

The following SAS program is submitted:

Data WORK.SALES;

do Year=1 to 5;

do Month=1 to 12;

X+1;

end;

run;

How many obersevations are written to the WORK.SALES data set?

Answer is 1. Is it because there is no 'output' stated in the code thats why it did not give individual value for each month, the 1 observation is the sum of individual months up to 5 years? Please help, thanks!

Without OUTPUT staement it iterates to up the end and outputs one observation.

Adding OUTPUT staemant will result in 1 or 5 or 60 (=5*12) depending after which line it is entered.
