Combining several data sets

[mauflagrum]

I have 243 data sets with names as:

fixed11

fixed21

fixed31

fixed41

...

fixed2411

fixed2421

fixed2431

All of them have the same variable names, and number of columns.

How can I combine them (one above the other) in one data set avoiding several data steps?

Assuming you want to append (stack) all the tables, use the colon shortcut.

data want;

set fixed: ;

run;

If you want them merged, ie the variables side by side that's a different question.
