I amusing SODA. When I create a new library
LIBNAME CHAPTER2 '/home/u61184402/Chap2';
DATA CHAPTER2.NEWDATA;
SET WORK.DATA;
the library is visible. I thought it is a permanent library.
When I logoff and the next time I do a logon, the library CHAPTER2 is no longer available. So how can I make the library really a permanent library that exists even when I start a new session.
