Filename as a variable name

SN — Fri, 22 Feb 2013 15:53:33 GMT

I have around 420 files. The id for the subject is the filename.

I would like to merge these 420 files as one file and tag the data for each subject with their id. Please could some one suggest, how could I create the filename as a variable (called id) inside the dataset for all the lines inside the dataset.

Once this is done, I could data merge the 420 files.

regards

If your "merge" means "stacking", then check out option: indsname= in "set statement"

If they are all structured the same they could be read at the same time avoiding the merge with the filename option assigning the value of the file name as a variable

filename myfiles "C:\path\*.csv"; /* or similar depending on your names and extensions*/

data want;

infile myfiles filename= FileRead ; /* and other options needed to read your data*/

input ...

run;
