some namelist variable names are difficult to interpret. For example: "coord_from_range_step" How I user should know that this is the resolution of the output file. A self describing name will be very useful, e.g., target resolution
check PTF with a single predictor, or a constant. I remember that Stephan had to hack my code to be able to make a function y = a + b x
Another variable that does not tell me anything: coord_from_values_bound
It appears that variables name(i) index i need to be consecutive. if I use 2 4 6 14 9 , 15 .. the parser had troubles with the ordering
