 		 #96665 - switch
Responding to: ???'s previous message
"Bigger switches are made with a jump table, so it can be faster since only one comparison with the biggest case value was done."

I seem to remember that early versions of the Keil compiler didn't use jump tables for switch statements, this is probably why advice to avoid switch statements still persists.
