Thanks Astounding- thats an even easier approach. No separate file for each month- so how would I produce the counts by monthI would use the following to extract the first day of current year: (to , putn() is abundant here): %let date_range_min = %sysfunc(intnx(year,"&sysdate9"d,0, b), date9.); Doing so, you only need to call a SAS function once, and you get to use an existing macro variable that has the system initiating date (be aware of that though). or something I would cal it cheating:In this video, we will see how SAS creates first. and last. temporary variables when there is more than one variable in the by statement.

In order to use first. syntax, you must use a BY statement in your data step: BY code; The =1 is unnecessary, it is implied TRUE. And I don't believe you can use FIRST. together with WHERE (since WHERE does not aware of what is going on in the data step, IF is). /Linus.usually means: But if SAS encounters an output statement in your code, the output at the end (enclosed in the run statement) will be ignored. Hence, since your output statement is conditionally executed only IF LAST.KEY, in your dataset you will have only observations marked as last.key, because your RUN; will only mean return.

So for last. circle = 1, we just add the variable tot_usage to the output dataset tot_usage in Step 3. For Alan, the second record is the first occurrence of circle = roaming, so Step 1 – 2 is repeated. The value of tot_usage now is 540. Re: How to get the first day of a week. The SAS calendar function intnx () will allow you to shift a week to wherever you want to.
