Hi Ben,

FILEVAR can be handy if you are using INFILE to read external files. For the SET statement, to create repetitious code, a macro can be good for that. The SAS Macro facility can create the text string with the names and substitute it into your code (as if you wrote it) just before your code gets to the compiler.

%macro multfiles(lo,hi); %let files=; %do i = &lo %to &hi; %let files=&files _&i; %end; &files %mend; %put files is >%multfiles(1,31)<;

Data need ; set %multfiles(1,31) ; Run ;

Hope this is helpful.

Hi all,

Can you tell me how best to go about doing this - I am trying to set a bunch of datasets (_1 -> _31) :

Data need ; do i=1 to 31 ; set _||i ; end ; Run ;

Many thanks!
