It can be done. Just created Latch FB, but for saving integers 0-63 it takes 15% of Alpha2 memory. Going to 0-128 would probably take another 5%. Full 16-bit range (negative included) would probably consume 30% of Alpha2 memory.
Anyone knows if you can combine EEPROM with ROM memory, like having a program which is part in ROM, part in Alpha2 internal memory? I guess not, but just want to be sure.
