Failure in HP-15c on IOS

[BuSchu]

Today I bought the emulation of the HP-15C for the iPhone made by HP. Then I tried a little program to roll the dice:

LBL A
Fix 0
RAN #
6
x
1
+
INT
R/S
GTO A

This program is identical to the program running on my real HP-15C's (old one and Limited Edition). On the real calculators we've used this program on many evenings in games without problems. But on the emulation the value is blinking when the program stops.

What's wrong? In the program store I see exactly the same instructions!

Any suggestions?
