I need to automatically check properties (paths, engine, access (readonly or not)) of all libraries in a session. In SAS 9.2 these are conveniently stored in sashelp.vlibnam. In SAS 8.2 I only found the libname function (which gives only the path), and that the properties can be displayed in the log window with statement libname <libref> list; Is there any possibility to get the output of this statement into a variable or macro variable? Or is there any other way to get this information?

Well, a couple of workarounds perhaps:
- Get the pathname of a library.
- Check access to a library
libname rob "S:\Temp\Rob" access=read;
attrib a format=1.;
- File will not exist as write protected (make sure to delete your temp ds if it is created.
- Still thinking about engine (haven't got 8.2 so can't try things).

Thanks for your replies. Unfortunately, the dictionary tables in SAS 8.2 do not contain suitable libname information except the pathname.
I found another solution:
ods listing close;
ods output Contents.Directory(match_all=DIRECTORIES) = <libname>;
proc contents data = <libname>._all_ nods;
The resulting dataset work.<libname> contains the information that you would get in the log file with libname <libname> list;
In case there is more than one level, detailed information is put into <libname>1, <libname>2, etc., while <libname> only contains information about the number of levels.
