Deciphering the box routine in lines 500 through 660 is left as an
exercise for you. The following hints will get you started.
The subroutine at 500 is used to create three boxes of different sizes
and characteristics, using the line graphics characters. The data stored
in lines 1300 to 1370 determine which line graphics characters are used
to print the boxes, the width of each cell, and the headings.
The variables sent to the subroutine are:
C - the number of cells
H - the height of the cells
F - a flag for shading the headings
FT -
a flag that allows a horizontal tab to adjust the left margin
of the box.
