Our SAS usage notes usually do a great job of matching symptoms to solutions. But good old SAS note 10751 really stretches the limits of logic.
The symptom: a message during the SAS 8.2 setup process that says "string variable is not large enough for string".
The solution: "To circumvent the problem, clean the CD with a soft cloth."
Hey, it works.
Fortunately, this sort of problem will be dusted away with electronic software delivery in SAS 9.2.
Thanks to Armistead (quoted in the ESD article) for bringing my attention to this SAS note. He keeps a framed copy of the note in his office; I'm sure he's looking forward to the day that he can retire it from the knowledge base.
