Get list of files in directory under NOXCMD - sas

Question

Can not use Xcommands in SAS EG. No access to SAS Management Console. How can I get a list of files in a directory without using Xcommands?
Tried DINFO but can only get 1 piece of info. Need a list of all files in the selected directory. Am I missing something here?
data a;
rc=filename("mydir", c:\");
put "rc = 0 if the directory exists: " rc=;
did=dopen("mydir");
put did=;
numopts=doptnum(did);
put numopts=;
do i = 1 to numopts;
optname = doptname(did,i);
put i= optname=;
optval=dinfo(did,optname);
put optval=;
output;
end;
run;

Answer 1

I've not used Enterprise Guide but how about using a pipe'd filename? You cn then use that with the infile statement to put the result of the query into a dataset...
filename dirlist pipe "ls /<your-path>/*";
data dirlist ;
infile dirlist ;
format fname $300. ;
input fname $ ;
run;

Here's a couple of macros we use to do this. The main macro is %file_list but it also requires the %isDir macro in order to run. Some usage examples:
%put %file_list(iPath=e:\blah\); * TEST AGAINST A DIR THAT DOESNT EXIST;
%put %file_list(iPath=e:\SASDev); * TEST AGAINST A DIR THAT EXISTS;
%put %file_list(iPath=e:\SASDev\,iFiles_only=1); * LIST ONLY FILES;
%put %file_list(iPath=e:\sasdev\,iFiles_only=1,iFilter=auto); * FILTER TO ONLY FILES THAT CONTAIN THE STRING AUTO;

%let path=C:\ETC;
filename parent "&path\Data\CSV";
data files;
length file_name $50;
drop rc did i;
did=dopen("parent");
if did > 0 then do;
do i=1 to dnum(did);
file_name=dread(did,i);
output;
end;
rc=dclose(did);
end;
else put 'Could not open directory';
run;
* Some additions;
%global name;
%global count2;
%let name=;
%let count2=;
proc sql;
select file_name into :name separated by '*' from work.files;
%let count2 = &sqlobs;
quit;
This works fine. I use &name for other macro and do something with files... (load from CSV, for example).
