I've been asked to write a HyperCard stack which would analyze an 
atmospheric pollution problem.  It's going to use a large xcmd written in 
MPW fortran, run a numerical simulation, and then draw contour maps of 
the output for display in HyperCard.  What I need to do is to be able to 
create COLOR cards with the contour maps drawn on them, so as to create 
an animation.
I have several questions:  Firstly, can one write XCMD's in MPW Fortran? 
I know that MPW C is a problem, but I have no idea whether MPW Fortran 
from Language Systems messes with register A5 or not.
Next, can one create a card dynamically and paint on the foreground 
easily?  In the background would be a map of the area or something.  
I also need to do the contour maps in COLOR.  I have the COLOR X-CMD, but 
that doesn't look too helpful here.
.
Am I trying to do something impossible?  The most irritating thing of all 
is that this is a piece of cake on the IBM PC, using software like 
Graphics FX, PC Storyboard, Graphix Designer, etc.  I'd appreciate any 
suggestions to help save my Mac Honor.
