Rob, and Jonas, in reading your responses there is a concern I have from
both of your approaches, namely that every time a select_table() is
performed the entire file has to be read. This wouldn't  seem to support any
substantial software application. The 22 files I've mentioned for an 'order
entry' program represent 20-100Mbytes of data, when you consider 3-5k
customers, 50k inventory, 2+ stocking locations... etc. Jonas, if this is
happening on your file server just to retreive one record from several
files, I don't see how it could support multiple users. The server would be
scanning the same files front to end over and over...
