Sorry, it's a mistake. Is there any way to undo and mark the correct answer provided by IanWakeling as solution?

Thank you.

I have two matrices A and ALS; my goal is to merge rows from ALS matrix where visit = 18 with matrix A by the ID variable. Any tip on how to do it in IML?

This is cool. I have devised a similar solution (but less technical) based on Astounding's proposal. data a; array p[2] _temporary_; array x[3]; do i=1 to dim(p)**dim(x); result = put(i, binary3.); do j=1 to 3; x[j]=substr(result,j,1); end; output; end; drop i j; run;

Thanks, I have the following data - Data a; Array p[2] (0 1); Array x[3]; I would like the data step operations to produce 8 rows with the unique combinations.

Great! This has promise. If I have two arrays P = (0 1) and x = (x1 x2 x3) where each of x takes values 0 or 1, how would you do it?

kaushik_patra · ‎04-10-2017

Thanks. The need is to have three distinct columns rather than a single column with all possible combinations.

kaushik_patra · ‎04-10-2017

Thanks, this is a nice little trick. I will have to have 3 different columns for all combinations of 0 or 1.

kaushik_patra · ‎04-10-2017

Thanks, it's a nice function. But the problem is I have n=2 (0 or 1) but k=3 which doesn't work for ALLCOMB.

kaushik_patra · ‎04-10-2017

Hi everyone, I would like to generate all possible combinations of three variables each with values 0 or 1 e.g. following using a data step 000 001 010 100 011 101 110 111 what will be a good way to do it?

You may want to try LOWER or UPPER option in the PRIOR statement.

Thanks Jag. It worked; I had to do a minor tweak to divide it by 60 as the duration is calculated in seconds and I wanted it to be in minutes. Kaushik

I am using the following syntax to calculate the minutes between two time variable. INFTIME = INTCK('MINUTE',INPUT(EXSTTM,TIME8.),INPUT(EXENTM,TIME8.)); EXSTTM = 23:48 EXENTM = 00:48 The result is coming out as -1380 but I expect the result to be 60 min obviously. Guess the problem is the end time 00:48 which is the next day. Any suggestion?
