using a switch case with a 5-position switch and serial output

I'm trying to get started on developing a menu system for my LCD1602. I have a Parallax 5-position switch (up,down,left,right,center) and I would like to interface the two.

I've been trying to get some code working but I'm kind of lost. I don't have a lot of recent experience with Arduino and could use some advice. I realize that there is a version of the 1602 that comes with a keypad integrated into the circuit but I don't have that model. I have a plain-jane screen and a separate 5-position switch.

I'm also aware that the easiest way to accomplish what I desire is with a resistor network and mapping the ADC values. However, I don't want to make an analog switch, I want to make a digital switch.

Is there any way I can take the pins and put them into an array and then translate that into a switch case statement?

I've tried several different ideas and nothing seems to be working. Forgive the example code, it's hacked together.

below is my code
