HP41C programs

I started learning programming on a HP9715 desptop calculator at my laboratory in the end of the 1970's.
When de HP41C calculator arrived on the market the same programming language was used and programming continued at home.
I made several programs and send them to the HP "Users' program library Europe" so they could be used by every one.
Unfortunately, it seems, all these program has been throw away. ?HP!!?
Fortunately I remained a copy of most of them. I scanned most of my own programs and they are available for reference.

If time comes I will add more. More in The museum of HP calculators
