Collective wisdom among programmers is knowing more about the variables helps the aim of the program.. The computer doesn't know what the program does anyway..This is something like preparing US Income tax returns if you are are the payer as opposed to an accountant. US Tax day is coming sooner than we think. Best wishes, David Booth
Thank you Ray Pörn, it was exactly something like this that I was requested. I will also check the reference list, it seems to be several interesting papers for my purpose there as well.
