Libname syntax

[RachanaT]

Hi All, 

can we define libname like libname mylib "$abc";  i m not sure if this is a valid format.

Thank you in Advanced

If you are not sure if something is valid, TRY IT in SAS and you will find out.

What is $abc, and why would you want it in a LIBNAME statement?

If your SAS session runs on a UNIX platform, and an environment variable named abc (case sensitive!) was defined at SAS startup, and it contains a valid path, this can work.

Right.

Or if you use the SET option create the environment variable.

options set=abc=/home/me/abc ;
libname abc "$abc";

Under Windows you can also refer to environment variables through SAS.

For example like this:

libname test "!TMP";*refers to the environment variable %TMP% if defined;
libname test clear;
