Multiple graphics devices

In advanced use of . it is often useful to have several graphics devices in use at the same time. Of course only one graphics device can accept graphics commands at any one time, and this is known as the current device. When multiple devices are open, they form a numbered sequence with names giving the kind of device at any position.

The main commands used for operating with multiple devices, and their meanings are as follows:

$\begin{session} \separate motif() postscript() $\ldots$ & Each new call to a dev... ...graphics devices on the list, except the null device. \cr \separate\end{session}$
