And I can't edit or pull code from a screen shot/bitmap.

Make a structure you're configuration items live in.

Create routines to read, write and validate this structure you can place in FLASH or EEPROM

FOO foo = { 0 };

void InitFoo(FOO *foo, EEPROM *eeprom)
{
...
  foo->donkeys = 12;
  foo->freqHz = eeprom->freqHz;
  foo->speedRPM = eeprom->speedRPM;  
...
}

I will keep trying,
My project needs to set parameters from a keypad.

Ok,Thanks  you
