Hi Thomas,

I hope that meanwhile you successfully finished your work. If not you can experiment with 
functions from stringproc.lisp and eval_string.lisp
You can open a stream to your data file, read in, parse and process line by line. Maybe this 
could be faster than first reading the whole file as one data list.
