[OS X TeX] pst-ode, or...

[Nitecki, Zbigniew H.]

Attached are two sample sourcecode files and the pdf output from one of them.
The file PPFig.tex uses the pst-ode package to plot the integral curves of a homoeneous linear o.d.e., using a grid of initial values, indexed by \rx and \ry
and generated via a pair of nested multido commands.  The output is in PPFig.pdf (I generated it using Ghostscript).
In the file PPFigtest.tex, I am trying to generate the analogous picture, but with initial conditions going around the boundary of the box.
I foresee doing this separately for each edge;  what is there at the moment is the modified code for initial conditions along the bottom edge.
My modification of PPFig was to eliminate one level of the nested multi do.  It crashes and I can’t find where I messed up.
I’d be grateful if someone has a pair of eyes sharp enough to find my typo or syntax error.
