SAS Macro and Dataline/Cards Statements in Data Step
I recently tried code like this in a SAS macro: data sections; infile datalines dlm=”,”; input graph_table_number $15. text_line @1 @; datalines; “11.1 ,Section 11.1″, “11.2 ,Section 11.2″, “11.3 ,Section 11.3″ ; run; While it works in its own right, including it as part of a macro yielded this type [...]

Having run VirtualBox OSE (1.5.6) for a while now, I succumbed to the idea of grabbing the latest version from the VirtualBox website and putting it on my main Linux box. The idea of having 64-bit support proved irresistible and I did get OpenSolaris to start, even if its being a VMware VM meant that [...]
