How do I change the power supply voltage for the CD4000 logic devices in my schematic?

The CD4000 digital family offers a simple way to change the power supply of all CD4000 components in a single circuit. Add the following text statement to the circuit file:

.param CD4000_VDD=10V

All of the CD4000 components in this circuit would then use a single 10V supply. The default power supply is set at 5V in the Digio.lib file.
