Thanks Day, but this is just a simplification of what I need

@Andrew Stone, thanks instance_variable_set makes it's work, but what if i
need the data inside too... for example

def call_other(var1,var2)
  max  = 8
  if(var1 == 0)
    var1 = rand max
  else
    var1 += max
  end
  var2 = rand max
end


BTW, can you explain the line of code "c :@xpos", didn't get it

Thanks again
