+#X text 23 50 'a' controls an arrow pointing upward. The main segment

+#X text 28 154 Slightly more complicated construction to make an arrow
+at 45 degrees:;
+#X text 25 330 It's a good practice to put a small patch like this
+one in each template that you can use to make the first one (and will
+often find yourself wanting to use again later):;

+#X text 35 7 Screen dimensions can be tailored to specific ranges by
+adding suffixes in the drawing instructions. For example \, in "template9a"
+\, a coordinate such as "b(0:100)(7:77)" instructs the drawpolygon
+object to rescale b from the range 0-100 to the range 7-77.;
+#X text 39 93 The application is to introduce an offset to a coordinate.
+For example \, the construction "a(0:100)(10:110)" just gives a+10.
+;
+#X text 35 147 Each of the three arrows of template9a is controlled
+by a single parameter (a \, b \, or c) and the entire red octagon in
+template9b likewise.;
