re-write code

Toni2 — Wed, 20 Apr 2022 09:29:23 GMT

hi, i am quite new in SAS. I have found the below code in a SAS paper and try to apply it. My issue is i have problem with access to different libraries and therefore the "file" and "%inc" does not work for me.

I am trying to find a way to re-write the below code in one SAS program to avoid the "file" line and then the "%inc" or the file/%inc to be in my current process flow

Is there any way to do it ?

data _NULL_;
set PSI.endpoints end=last;
file "&PSILibrary\decileSample1.sas";
if _N_ = 1 then put " select;";
put " when (BinVar le " maxVar ") decile = " decile ";" ;
if last then do ;
put " otherwise decile = " decile ";" ;
put "end;";
call symput('maxbin',decile);
end;
run;

data PSI.PSISample2;
set PSI.PSISample2;
%inc "&PSILibrary\decileSample1.sas" / source;
If BinVar=. Then decile=&maxbin;
run;

The first step in this code generates SAS code (text) that gets written to an external file as text. I've amended the syntax so this code gets written to a dynamically created file in SAS WORK (and only exists as long as your SAS session exists).

The second data step then %includes this text file (that contains SAS syntax) and executes it.

I've also changed option source to source2 in the %include statement. This will write to the SAS log the generated code that gets executed.

libname psi <path to the folder where table endpoints exists>;
filename codegen temp;
data _null_;
  set psi.endpoints end=last;
  file codegen;
  if _n_ = 1 then put " select;";
  put " when (binvar le " maxvar ") decile = " decile ";";
  if last then
    do;
      put " otherwise decile = " decile ";";
      put "end;";
      call symput('maxbin',decile);
    end;
run;

data psi.psisample2;
  set psi.psisample2;
  %include codegen / source;
  if binvar=. then decile=&maxbin;
run;

You will still need source table psi.endpoint and you will need to define a libname psi <path>; that points to the directory where this table resides.
