How to write a do-loop for an array containing different number of variables?

[Butters_Scotch]

I have a macro that will be initialized on different arrays, but the arrays have different number of variables, thus I was wondering how I would write the do loop to cover the length of both arrays. So the first array has 10 variables but the other array has 20 variables. My goal is do i=1 to (max). (but not sure how to write this in SAS). Thanks

It will be easier to respond if you post your code.

True, sorry about that. Thanks though!

Hi,

I agree with Arthur, post your code so we can see what your trying to do, not sure why you would want arrays and macros?

Use the dim() function to get the length of the array.

do i = 1 to dim(array_name);
