I've decided to post it as a separate question:
How could the following steps be achieved programmatically?
* goes to "Libraries"
* selects the appropriate lib
* and checks the "assign at startup" option under Modify Library.
I guess that these settings could be maintained within either config.sas or
autoexec.sas, but are you actually supposed to *write* to these files on
your own, at the appropriate place and all? Ideally, there would be an
extension function or something.
Thanks in advance,
