Hi,

the problem is, that v[] is a function call and *not* a
reference to a variable. So
v[i]=v[i]+1

define a recusion and not a reference to a value in a list
like v[[i]].

*And* that v[i] is a function call is a "problem" of
Mathematica's syntax.

The true problem is that Toshiyuki Meshii try
to use function values as arrays because FORTRAN's
syntax make no difference between A(i,j) as an array
reference *or* as an function call.

Regards
  Jens
