CAS program corrupts itself

[peacecalc]

Hello prime fans,

I have no prime nor I use the emulator.
The hp 50g use in his FOR loops counter variables which are reals (the start and end value can be integer, too). Maybe the FOR loops work with start and end values 1.0 TO 2499.0 . Although it's a contradiction to CAS mode...

... only a sneaking suspicion...
