Big Data - Module 2 DS2 array example

odesh — Wed, 25 Sep 2019 21:43:23 GMT

Hello,

As usual, please refer to the attached printscreen for I ( uppercase or big i ) in the DS2 ( and Base SAS programs).

Is "I" part of the PDV or is it defined somewhere ?

"i" ( lowercase or small i is the array index variable. But this is not the same as I ? Is it ?

I must be missing something here.

Thanks.

Odesh.

Hi:

The instructors advise that the SAS syntax is case insensitive. That means that lower case i and uppercase I are referring to the same variable. I is not in the PDV because it is declared as a local variable within the RUN method. Because of that it will not be written to the output dataset. It is only defined locally to the RUN method.

I hope this clarifies your question regarding the array processing in these programs.

Cynthia
