sas - searching several directories in a dataset with macro commands -


i have list of directories in form of work.directories.data, let's (variable directory). each row contains string looks this:

c:\importantfolder\subfolder\

i want find contents of each of these directories , combine them make new dataset. here have far:

%macro scandirec(string=);     filename temptree pipe 'dir "&string" /s /b' lrecl=5000;      data smalllist;         infile temptree truncover;         input dirlist $char1000.;     run;      data biglist;         set biglist smalllist;     run; %mend scandirec;  data smalllist; run; data biglist; run;  data _null_;     set directories;     call execute('%scandirectories('||directory||')'); run; 

i serious problems, think code looks pretty harmless. issue?

the error message seems pretty straight forward.

1    data test ; 2      infile 'dir "&string" /s /b' pipe truncover; 3      input dirlist $char1000.; 4    run;  note: infile 'dir "&string" /s /b' is:       unnamed pipe access device,       process=dir "&string" /s /b,recfm=v,       lrecl=32767  stderr output: file not found note: 0 records read infile 'dir "&string" /s /b'. note: data set work.test has 0 observations , 1 variables. note: data statement used (total process time):       real time           0.99 seconds       cpu time            0.04 seconds 

windows not find files named "&string".

use double quotes around strings if want sas resolve macro expressions.

"dir ""$string"" /s /b" 

or avoid macro completely.

data biglist;   set directories;   length cmd $500 ;   cmd = catx(' ','dir',quote(trim(directory)),'/s /b');   infile cmd pipe filevar=cmd truncover end=eof;   while (not eof);     input dirlist $char1000.;     output;   end; run;
