It depends on how you use spreadsheets. Summing a column is not programming, but yes, there is a second page, or sheet, to spreadsheets. > In the same way, R is stats+programming What is R? > sql is relational-algebra+programming Yes. And as long as you don't do that fancy cursor iteration and stuff, perhaps it is simply a computer implementation of relational algebra, with some glue to make it stick together with everything else, that is the computer (like the indexes, and ordered sets - of course you don't need that in an abstract, math model, that shouldn't be searched or otherwise optimized)? > [And oldtimers will remember SetL] Never heard of. What is that, set theory + programming, as in the "set language"? -- Emanuel Berg - programmer (hire me!
