:For(A,dim(⸤SX)-1,0,-1 :⸤SX(A)→⸤SX(A+1 :End

At the beginning, the For() starts at the dim of the list. But then, it ends at 0, which is not an list element.

:For(A,dim(⸤SX)-1,0,-1
:⸤SX(A)→⸤SX(A+1
:End
If this is a high score list, I suggest you do this: 
6→dim(⸤SX S→⸤SX(dim(⸤SX SortD(⸤SX 5→dim(⸤SX

:For(A,dim(LSX)-1,0,-1
:LSX(A)->LSX(A+1)
:End

dim(LSX) is 5
the error sends me to the A in LSX(A)
can someone explain this?
