It's probably the early program version. If you ran CIII RAM version without regard for whatever the inputs are, you can most certainly screw up CIII RAM. I forget which string it was, but one of them is for input. And the Ans? I think that's also input. If you're messing that up, you might run into some unexpected problems.
I'm sorry if that answer's a bit sketchy. Even though I made that program, it's been *years* since I seriously looked at that program. My development is focused on the app version of CIII, along with E:SoR (not relevant to this discussion).
Now... if you're talking about the APP version of CIII, none of the strings or real variables will have anything to do with it unless you're feeding in faulty inputs to CIII.
