  Yes. Actually I have done that in the past, and it worked. 
  But there are architectural considerations that make this approach
  not what I am looking for. 

  I could also prep the data in the DOM, to split textual values, say
  into <line> elements. But that would be very complicated once I want
  to layout several columns. Incidentally it was at the attempt of
  several columns that I first hit this maxvars issue.

  All this because there a limit here that most people would 
  agree with makes no sense on modern hardware.

  Yes, there is I think.

  I am not sure how that would make the requirement for variable
  creation at recursion go away. I need to create at least one
  variable at each recursion step, don't I? I could try to compress
  all information I need at any recursive step into one variable, but
  it would make the code close to unreadable.
