I am only now catching up from a (far too long) inability to tend to ASPECT 
matters. I've tried to run this with the same input as you, but I don't get 
your error.

Do you still get this error? I suspect that this must come from the following 
parameter:

subsection Initial conditions
   set Model name = function
   subsection Function
     set Function expression = 1000.0
     set Variable names      = x,y
   end
end

Of course, the value "1000.0" is completely reasonable, so I don't quite 
understand what exactly the problem is. I could speculate that there may be 
some invisible character (spaces?) at the end of the line, or that maybe you 
have a locale set that requires a comma instead of a point to separate digits 
(as, for example, the German locale requires, unlike what is used in English 
and American English locales). But in the end, I'm a bit stumped...

Best
  Wolfgang
