Since coding in C forces you to go relatively step-by-step I now "get it" more definitely. 4) There then arise practical questions of how exactly the required information can be got into the right place at the right time, in the context of gretl's C code. Since I know that code like the back of my hand, I can contribute something useful at this point. 5) We then go back and forth a few times, trying to iron out any problems that may arise (e.g. special cases not handled). 6) If all goes well we end up with something that implements Jack's original idea and is reasonably robust across a wide range of possible cases.
