This is especially true in my field, demography, where there is an
abundant literature of excellent Fortran programs, originally written
for mainframe computers (cards in, paper out).  I have found a way
to do high quality user interfaces in Fortran, using a Fortran-
callable library of programs called Spinlab. This is available for
Lahey F77L compilers, with plans for an MS Fortran version in the
future. (Maybe this exists already; I haven't checked lately.) This
library contains assembly language routines for screen addressing,
keyboard monitoring, scrolling, windows, everything needed to create
top quality user interfaces. I bought it from the author, but I think
Lahey is now licensed to sell it.
