# Graphic editor on a screen
that contains two blocks with
X1 = beginning column
X2 = ending column
Y1 = beginning line
Y2 = ending line
Block 1 has the following coordinates: X1=1 , X2=40,
Y1=4, Y2=21
Block 2 has the following coordinates: X1=40, X2=80, Y1=4,
Y2=21
Local integer COORD(1..200)
Local shortint NBBLOC
# number of blocks
NBBLOC = 2
# storage in table of the coordinates of block 1
COORD(1) = 4*8
COORD(2) = 1*4
COORD(3) = (21-4)*8
COORD(4) = (40-1)*4
# storage in table of the coordinates of block 2
COORD(5) = 4*8
COORD(6) = 40*4
COORD(7) = (21-4)*8
COORD(8) = (80-40)*4
# call of the graphic editor
Blk NBBLOC Using COORD
"Blk" defines the block
coordinates graphically.
The "Ins" (Insert) key allows the creation of a block.
The "Del" (Delete) key allows the deletion of a block.
The mouse allows you to enlarge, shrink, or move a block.
This instruction is used in screen management by the "Drawing" option
of the right-click menu option on a block.
