Do Loops with Multiple Conditions

tbanh — Tue, 13 Oct 2015 04:06:40 GMT

Hi,

I was wondering if it was possible to have a do loop that satisfies two conditions. For example, in my SAS code:

do SampSize = 5 to 50 by 5;

I want my code to do the above do loop but satisfy the following condition as well:

do SampSize = 60 to 100 by 10;

Is there any way to combine the two conditions (e.g. do SampSize 5 to 50 by 5 and SampSize = 60 to 100 by 10)?

Thanks,

Tim

Try:

Data A;
Do SampSize= 5 To 50 By 5, 60 To 100 By 10;
Output;
End;
Run;

If you are looking for an IML solution, then the data step syntax above will not work. Other solutions would be to have two loops or save all the values of SamSize in a vector as follows:

  ss = do(5,50,5)||do(60,100,10);
  do i = 1 to ncol(ss);
    SampSize=ss[i];
