Here’s some mods,
the datas are not duplicated, i was able to make it beep once with the original program, when it beep twice or more, the temp(6) variable is always different but < or > to the threshold value.
i have corrected some issue in the code, the temp bytes table must be defined to temp( 19 ) rather than 18
temp( 19 ) means 19 bytes from temp( 0 ) to temp( 18 ), this way you’re not overwritting the next variable stored in memory after the temp bytes table when using shiftin.
anyway here’s the code corrected, but i’m not sure it’s the way to go 
this way the WalkForward code will be called only one time if the joystick is pushed up…then to call it again you’ll have to release the joystick then push it again.
“normal” behavior should be to define a WalkForward code to move one step then return to main loop, then if the joystick is still pushed up it calls again the WalkForward code and move one step more etc…
I’m not understanding how you will define the Walkforward code the way you do.
see the next post for another way…
