> You wouldn't happen to have a spare ELH diagram (or two) lying around > that one could take a look at, would you? Hah TIM now you've got me! I 'do' diagrams. I don't 'do' neat! [no need to move over Matisse] The longer answer is that I have diagrams coming out of my ears (well, computer), but they are very much working documents, rather than something fit for publication - indeed fit for showing to someone else at all... I (somewhat feebly) suggest that you would do better to grab a book on structured analysis and design from a convenient library. In the 'old days' I would have recommended Yourdon or Jackson, but many have entered the field/published since. Such will have example diagrams chosen for the simplicity of the subject matter, and carefully/logically explained - that's three times better than anything I can (quickly) offer... In addition, they will mention the three or four main diagram types that can be employed in SA and D, which may be yield additional benefits. I fear my stuff, assuming I can weed out something that is both reasonably straightforward and that will 'stand' on its own, will not be quite so 'inspirational'. With apologies... Regards, =dn
