The length of a page is determined by the number of dot rows from row 0
(Y = 0) up to and including the highest row used before a new page is
started (by an SOP, SOD, SDC, or WFC record). When a new page is
started, the previous page is printed up through the highest row used.
Page length is defined as the number of dot rows used. Because the first
row is identified as Y = 0, the page length is one more than the highest
row used.
For example, if a page consists of only one line of text using an upright
category I font, the page length is the number of rows up to and including
the last row of interline spacing following the line of text. Assuming that
the character cell height is 10 dot rows and the interline spacing is 3 dot
rows, the page length is 13 dot rows. Refer to Figure 1.14.

If the cursor is left at the end of the page by a set position record (SPO),
the page length is equal to the Y position parameter in the SPO record
(assuming an origin of Y=0). The row previous to that identified by the Y
parameter is the last row on the page. In Figure 1.15, the page length is 9
dot rows.
