The "middle" or "core" of a diary being, of course, the dated pages generated by the Main DiaryGridLine.
As such, it is a simple container and only has 2 properties; force start and page count.
Because this script line occurs by definition at the very start of a Script, its Force Start property is rarely used (the first page of Front Pages always corresponding, in principle, to the first page of the output file).
See also: back pages.
