<div class="" style="word-wrap:break-word; line-break:after-white-space">Attached are two sample sourcecode files and the pdf output from one of them.
<div class="">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</div>
<div class="">and generated via a pair of nested multido commands. The output is in PPFig.pdf (I generated it using Ghostscript).</div>
<div class="">In the file PPFigtest.tex, I am trying to generate the analogous picture, but with initial conditions going around the boundary of the box.</div>
<div class="">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.</div>
<div class="">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.</div>
<div class="">I’d be grateful if someone has a pair of eyes sharp enough to find my typo or syntax error.</div>
