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.
999 REM: The End
In this chapter we developed a program that uses many of the fea-
tures of the FX printer. The program demonstrates the tremendous
potential of the powerful tool you have at your beck and call. We
hope it inspires you to use the FX printer in many creative ways to
enhance your own programming applications.
