run page xy XY

(x,y,X,Y) are single digits
xy = location, XY = size
only 1 blank between xy and XY
quadrants:
----------| q1 | q2 |
----------| q3 | q4 |
----------Matrix notation:
xy is the location of the page
XY is number of subdivisions
The idea here is that the page is divided into a grid of X by Y
rectangles. Plotting is done in the x-y rectangle. In the
following example, the page is divided into two columns (X=2)
and 3 rows (Y=2).
----------| 13 | 23 |
----------| 12 | 22 |
----------| 11 | 21 |
-----------
xy values for XY=23
To draw into the top left rectangle, you "run page 13 23".
To get the bottom right rectangle, you "run page 21 23".
The following
"run page
"run page
"run page
"run page
commands are equivalent:
q1"
"run page 12 22"
q2"
"run page 22 22"
top"
"run page 12 12"
bottom"
"run page 11 12"
Limitations: X and Y must have values from 1 to 9.
