Store text filenames from a windows directory in to a sas macro

mayankdce1 — Thu, 31 May 2018 11:34:45 GMT

Hi,

I have a windows directory in which I have created a few macros as .txt files. I want to store the names of these text files in to a sas macro. The intent is that I want to declare (%include) all macros within that directory using this sas macro instead of asking user to enter all the macros one by one. Please note that each text file contains some lines of sas codes (and no data)

Thanks!

Mayank

What you want to use is sasautos:

There is no benefit to you coding this yourself.

Thank you for a prompt response. As a quick fix, I have created a small macro. But, I am also simultaneously looking into sasautos to get more understanding.

%macro declare_macros;
%let file_path = &toolkit.;
filename dirlist pipe "dir ""&file_path"" /b ";

data dirlist;
infile dirlist missover pad;
input filename $1000.;
run;

data _null_;
set dirlist;
id = _n_;
call symputx("nobs",strip(id));
call symput('macro' || left(put(_n_, 4.)), trim(filename));
run;

%do ii = 1 %to &nobs.;
%include "&toolkit.&&macro&ii.";
%end;
%mend declare_macros;

Thats not a quick fix, thats a very long fix, which may not work all the time and isn't portable.

options sasautos=(&toolkit.);

Is a quick fix.

Thank you, again. It worked! Much simpler method.
