### 17.1.3. Example 3: Creating a Simple Subroutine

The following example defines a simple subroutine to make two planes at specified locations. The subroutine will be used in the next example.

    !sub makePlanes {
       PLANE:plane1
          Option = Point and Normal
          Point = 0.09,0,-0.03
          Normal = 1,0,0
          Draw Lines = On
          Line Color = 1,0,0
          Color Mode = Variable
          Color Variable = Pressure
          Range = Local
       END
       PLANE:plane2
          Option = Point and Normal
          Point = 0.08,-0.038,-0.0474
          Normal = 1,0,0
          Draw Faces = Off
          Draw Lines = On
          Line Color = 0,1,0
       END
    !}

Although this subroutine is designed for use with the next example, you can execute it on its own by typing `!makePlanes();` in the Command Editor dialog box.
