Read in Files with pattern match into one SAS dataset - sas

Question

I would like to read a number of .csv files into a single SAS dataset using a pattern match. For example if in the directory /home/datasets there are 5 files:
/home/datasets
~/output_group1a.csv
~/output_group1b.csv
~/output_group1c.csv
~/output_group2a.csv
~/output_group2b.csv
All with known and identical structures and data types. I would like to read in only those files corresponding to group 1 without having to explicitly specify the filenames.

You can use a wildcard in your infile statement. If you have headers in each file you'll need to account for that. Here's a bit more of an example.

data try01;
length filename txt_file_name $256;
retain txt_file_name;
infile "Path\*.txt" eov=eov filename=filename truncover;
input#;
if _n_ eq 1 or eov then do;
txt_file_name = scan(filename, -2, ".\");
eov=0;
end;
else input
