 I use MatLab from The MathWorks, Inc (info -8 at 8- mathworks.com) to produce
 contour plots and mesh plots.  It uses color on the Mac II and produces
 contours of quite high resolution from moderately sized matrices
 generated from analytic functions or read in as a datafile.  An external
 file must contain data at every point in the nxm matrix.
 I should appreciate some contouring source code in Pascal or FORTRAN
 myself since I should like to incorporate contour plotting within other
 pgms.  This would have to be Mac-specific to be useful to me.  I assume
 that Ya-Jun Zheng at Penn State would prefer such code to using MatLab.
