I need to do a wordcount based on comma delimiter and pass the delimiter parameters into macro.

Currently it is retreving both the arguments like  FILE1,FILE2 & DATA1,DATA2

 

 

 

%let Filename_1 = FILE1,FILE2;
%let SAS_DATASET = DATA1,DATA2;

%macro file_process;
%let word_cnt = %sysfunc(countW(&Filename_1,','));
%do  i = 1 %to &word_cnt;
%let file_name=%scan('&Filename_1',&i,',');
%let dataset=%scan('&SAS_DATASET',&i,',');
%end
%mend file_process;

Hi

 

Since the SAS Macro Language is text based you do not need to use quotes. Since some of your text contains characters which have a meaning in the macro language (comma separating arguments in functions) you need to use quoting functions.

 

To understand quoting functions, I recommend to read the following blog

http://blogs.sas.com/content/sgf/2014/08/15/macro-quoting-made-easy/

 

 

Below is the changed code:

 

%let Filename_1 = FILE1, FILE2;
%let SAS_DATASET = DATA1, DATA2;

%macro file_process;
  %let word_cnt = %sysfunc(countW(%bquote(&Filename_1), %str(,)));
  %put NOTE: &=word_cnt;

  %do i=1 %to &word_cnt;
    %let file_name = %scan(%bquote(&Filename_1), &i, %str(,));
    %let dataset = %scan(%bquote(&SAS_DATASET), &i, %str(,));
    %put NOTE: &=i &=file_name &=dataset;
  %end;
%mend file_process;

%file_process
