Thinking about it in retrospect, I'm actually surprised that a C-coder
like you chose 1-based indexing for gretl's language. But it probably
helps the average user a lot. I remember that on the python-numpy list
(python is 0-based) this used to be a repeated issue raised by new
users, many coming from Matlab.
