Eons ago I had blank worksheets that came with my TI59 that facilitated writing down the program on paper, organizing the structure of it, before you started keying it in.
Does anyone have a link to a PDF or a message number on this forum that has such a link for a worksheet for HP calculators?
(I admit to not being able to effectively use the search engine on this site. I either get no hits or a huge number of irrelevant hits)
