(12C) Check if two numbers is to the power of other

[Gamo]

I try to check the program line by line using SST as Dieter mention.
The example problem is 5 to what power is to 25.

When Y^X loop to 25 at line 017 it keep looping to line 009 one more time to 125 and exit.

This suppose to exit exactly on 25 since X is less than or equal to Y conditional test.

This program work normally on regular 12C

Thank you
