Invisibles

Did you know that…

  • draining the iOS-batterie below 20% simulates a decreasing contrast of the LC-display. Charging the device sets back the full contrast.
  • the display of the iOS-device does not turn off as long as a calculator program is running. So, be careful with infinite loops!
  • the memory is limited to 999 steps for programming though, but programs which¬† are together larger than 999 steps, can be loaded at the same time into the memory. In that way you can for example load a program into P0 with 600 steps and then a program into P1 with 700 steps. The program counter on the right shows the overflow with — instead of 000.
    You can use programs in overloaded memory without problems.
