I posted an announcement like this about ten days ago to the SNUG mailing list,
but it (finally) occurred to me that it may well be of interest to readers of
this Newsgroup as well.

The following paper is available by request.  It is Los Alamos preprint
LA-UR-92-2541, and was submitted to Computers in Physics.  Let me know if you
can receive NeXTmail (that is, to receive and print out a .dvi and a .ps file)
or, as a less preferred means of distribution, to what address I should send a
hardcopy version of the preprint.


\begin{title}
An Interactive NeXTstep Interface to a Fortran Code
for Solving Coupled Differential Equations
\end{title}

\begin{abstract}

This paper describes a user-friendly frontend to a Fortran program that
integrates coupled nonlinear ordinary differential equations. The user
interface is built using the NeXTstep Interface Builder, together with a
public-domain graphical palette for displaying intermediate and final results.
The main problem is how to communicate between the Objective-C environment of
NeXTstep and the Fortran code. This is resolved by breaking up the Fortran into
separate subroutines, corresponding to the various control buttons in the
interface. These subroutines are then compiled in such a way that they can be
called as ordinary C functions.
