I think it has been around for a long time, as far back as version 1.7, but for some reason it was never documented. </div><div><br></div><div>The screen command allows you to save the contents of the display window into a buffer in memory. You can also restore the saved buffer to the current display at any time. It works in double buffer mode, but not in batch mode. It's handy for doing interactive animations and for easy comparison of several plots. if you've ever wished for a 2nd display window, you might like the screen command. </div><div><br></div><div>The reference page is at <a href="http://grads.iges.org/grads/gadoc/gradcomdscreen.html">http://grads.iges.org/grads/gadoc/gradcomdscreen.html</a></div><div><br></div><div>--Jennifer</div><div><br><div apple-content-edited="true"> <div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 12px; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div><br></div><br class="Apple-interchange-newline"></span></span></div> </div><br></div></body></html>
