QOVAL(.500,1.000,411,.0061)
Now, four values will be passed to the Q routine named OVAL. In this case, you would
be making a die button that was .500 inch high and 1.00 inch long, using condition
number C411, and offset .0061 inch. But you can also see how easy it would be to make
a different size oval shaped die button if the Q routine named OVAL were properly
written and stored on the user diskette or hard drive!
Figure 10-2 is a drawing that shows the motions that will be made in the Q routine: Note
that this Q routine ASSUMES THAT THE WIRE IS POSITIONED MANUALLY TO
THE CENTER OF THE OVAL FIRST.
Figure 10-2
In the example below you could also enter the values into registers H 0,1,2 and 3.
