I'm not sure what the current status of that offering is. However, <PLUG>, a subset of that functionality is available in the System Manager's Toolbox from Lund Performance Solutions, in the program called KLONDIKE. With KLONDIKE, you can say: freeze SALES23.PUB.FOO which would bring the entire dataset into memory, and freeze it. (More info at: http://www.allegro.com/toolboxes.html) The Kelly program allowed you to bring in selected ranges of the dataset (as well as the whole dataset). Finally, if you use KLONDIKE to freeze a file into memory, the freeze will be forgotten some number of minutes after the last person stops using the file ... which shouldn't be a problem in your situation. The Kelly product avoids that problem, keeping the file (or subset) frozen as long as you wish. Allegro Consultants wrote both products, and (in theory) have a small financial interest in them. </PLUG> -- Stan Sieler [log in to unmask] http://www.allegro.com/sieler.html
