* So to create a text buffer window which takes the top 40% of the original
* window's space, you would execute
- * |[ newwin = #glk_window_open(win, #winmethod_Above | #winmethod_Proportional, 40, #wintype_TextBuffer, 0); ]|
+ * |[ newwin = glk_window_open(win, winmethod_Above | winmethod_Proportional, 40, wintype_TextBuffer, 0); ]|
*
* To create a text grid which is always five lines high, at the bottom of the
* original window, you would do
- * |[ newwin = #glk_window_open(win, #winmethod_Below | #winmethod_Fixed, 5, #wintype_TextGrid, 0); ]|
+ * |[ newwin = glk_window_open(win, winmethod_Below | winmethod_Fixed, 5, wintype_TextGrid, 0); ]|
*
* Note that the meaning of the @size argument depends on the @method argument.
* If the method is %winmethod_Fixed, it also depends on the @wintype argument.

* as measured in D's font, and D would get the rest of O2's space. That may not

+ * |[ glk_window_set_arrangement(o2, winmethod_Above | winmethod_Proportional, 70, NULL); ]|
* These do exactly the same thing, since 30% above is the same as
