Wow I definitively think your calc is bricked or it has an hardware issue. ANyway I hope it won't hinder your programming in long terms...
Also I still find dealing with appvars incredibly hard in Axe. I just can't remember when to do Getcalc(PTR,SIZE), Getcalc(PTR,SIZE)->VAR, Getcalc(PTR,SIZE)->PTR, Getcalc(PTR), Getcalc(PTR)->PTR or Getcalc(PTR)->VAR, even after checking the example programs.
