8.2: Contouring

This example plots a section of dT/drho vs x and rho (actually, sigma-t, as the label indicates). The contours are unlabelled; I'm only interested in the zero crossings.

There are some other useful tricks in this example, such as calling `awk' and `wc' from the unix system.

(In the plot shown, all `query' questions were answered with carriage return, yielding the defaults; the `-p' flag was specified on execution, so the time stamp was not drawn.)

Example 8 The command-file.
