Based on this ASA 12 discussion http://sqlanywhere-forum.sybase.com/questions/10917/environment-variable
And statements in the Sybase 16 online documentation, I'd expect the Deployment Wizard to set SQLANY16 and add BIN32 to the PATH during installation. Before I add a comment to DocCommentXchange, I'd like to verify what the proper behavior should be.
I see the same behavior for ASA 11 so I suspect it is by design.
