As an example, we have a NextStep application in which all the GUI is Obj-C (for sure) but the computations are all done in FORTRAN. That is, there's almost 12K lines of old FORTRAN behind the scenes, some of it over 20 years old. Some readers may snicker at using FORTRAN behind the scenes. But why not? Its code we did not write, its maintained by others, it happens to be modular, and we didn't have to modify it to use it. And the big plus is when you look at how people us this FORTRAN code on mainframes compared with our GUI to the same program on the NeXT; its night and day. Its like a completely new program Paul Kunz Stanford Linear Accelerator Center NeXT Mail to: pfkeb@ebnextk.slac.stanford.edu
