It is obviously quite possible (I would guess probable) that with 16 MB total RAM, Hans-Peter would probably not have the 11 MB free RAM workspace which his application wanted, particularly if he is has a RAMdrive of any sort.

My personal experiences suggest (possibly incorrectly) that the Windows SWAP file is not usually the answer - since SAS appears to need everything in RAM simultaneously for some computations. If 'everything else' is SWAPped to disk and there still is not enough RAM available, I don't think that increasing the size of the SWAP file will necessarily help - in that sense, I don't think that one can necessarily think of the SWAP file as being an 'extension to RAM'. But maybe I am wrong!
