I tied the dir input on the stepper driver to gnd on the Arduino and it works in the reverse direction, remove the gnd and reconnect the dir output, or leave it unconnected, and it runs in the other direction. The problem is the sketch is not changing the output value per keypad input. I even changed the step and direction output pins from 12 and 13 to 2 and 3 on the Arduino. Same results.
I don't understand the whole process well enough, I guess. I'll try making a logic flow diagram of the sketch. That's what I used to do with Basic programs back in the day...
No where did I put that logic symbol drafting template...
I thank all those that have looked at the sketch and tried to help.

The difficult takes me a while, the impossible takes a little longer.
