Now run the program to see the six print lines combine into a

pattern:

Notice that the graphics command can be in effect for only one

print line. The command is in lines 30 and 60 so that it is issued each

time a new print line is begun. You cannot print more than one line of

graphics without having the graphics command issued more than

once.

The PRINT#4 at the end of lines 60 and 100 causes the end of the

print line. Without this command, the second graphics line would be

printed to the right of the first one instead of below it.

Designing Original Graphics

The sample graphics program is not especially complicated, but it

does include the same steps you would use for a more complex figure

so that you have the basis for designing graphics on your

HomeWriter-10.

There are four steps to printing an original design:

Plan the figure with dots on graph paper.

Divide the figure into separate print lines.

Calculate the numbers for the pin patterns in each column.

Put the numbers in your graphics program.

In the next pages you’ll see this process in action with the develop-

ment of the sample program.

Figure 4-3 shows the first step toward printing a design. It should

point you in the right direction for your own designs.
