There isn't a single pin for turning the whole 7seg off. You can use another bit (switch) as part of the select to determine if each segment should be on or off.

So then I can omit the SEL declaration and switch statement at the bottom altogether? This would mean that I only use the display on that one display I chose. Is that correct? Also, if I wanted to switch between one display or another, then would have to declare a_to_g1 and a_to_g2. In this manner, I would be able to declare the something to the effect of the following?

if SEL <= '1', then (a_to_g1 and not a_to_g2)

if SEL <= '0', then (not a_to_g1 and a_to_g2)
