Well done!
That's the answer. If you do this:
data "temp1";
  a=5;
run;

x cd h:\; /* Not the initial default folder */
data "temp2";
  a=5;
run;

you will have two new libraries allocated: Wc000001 (initial default
folder) which contains the temp1 table and Wc000002 (h:\) which contains
the temp2 table.

Søren

been experimenting with this over the past couple days should remember to
clean these up.  ;-)
