HP45 Behaviour
Hi all,
I was playing around with the HP-45 emulator and came across this problem Assume you have a value stored in Memory [1] (Example: 50 STO 1). If you do RCL 1, then 50 is placed into the C register and the stack is lifted by one and 50 is displayed as you would expect. However, when the Enter key is pressed, then the Status register bit 7 is cleared when the code gets back to the main loop. Now if you press RCL 1, the value is placed into the C register but the stack is not lifted. Stack 5 Enter 1/x RCL 1 T 0 0 0 0 Z 0 0 0 5 Y 0 5 5 0.2 X 0 5 0.2 50 (Expected) (However) Stack 5 Enter RCL 1 RCL 1 T 0 0 0 0 Z 0 0 5 0 Y 0 5 5 5 X 0 5 50 50 Anyone know if this happen on a real HP45 cheers Tony |
