Johny3329 whose post I reply to below was later banned and kicked out for adding spam, but I'll leave my reply. The relevance of his post to the 41 (and to this synthetic-programming topic) was questionable, but I initially gave him the benefit of the doubt.

I don't have a direct answer for you, but HP document 85153-90019, "Creating Your Own HP-41 Bar Code" seems to have very detailed information on the bar code types, and has BASIC programs to generate them. A scan of this document is at cd-8/sw/hpbc.pdf of this
DVD, and probably on this
DVD as well (from this site) although I don't have the latter to verify. There are probably other files on there too that would help. I don't know if Frank Wales lurks here, but he was on the design team for the HP-71 wand which reads about ten different bar code types and I believe can also read HP-41 bar code. See also if any of these pages help:
