In high school, we used what I think was called _The_FORTRAN_Coloring_Book_ (wasn't that what it was called Frank?). That's not the same thing is it?

Jeffrey, I didn't learn from it myself, but a lot of people I worked with that were "non-technical" (geologists, geophysicists, etc. that weren't formally trained in CS) used it at the time. I was working for a company that did 2D and 3D modeling software (c 1980), and it was written entirely in Fortran, implemented as a library. To use it, you had to be able to write at least a small program to read your data from a file, and make calls into this library (about 30 lines with the right data sets would give you 3D wire mesh perspectives of Mount Saint Helens before and after eruption, for example). Rex's book helped a lot of people be very productive, and it was a bible among the project staff. I also happen to have a copy of his book in my library, still, on the shelf next to Knuth, Sutherland, et al. It's a classic. Patrick
