I see only one page (the listing) of an obviously several page article in a Dutch magazine. May I ask if you also have the rest of it?

The program uses a somewhat cumbersome method for calculating the number of days from a date. And I assume the "usual formula" would also be significantly shorter, at least in the simplified version for the period from March 1900 to February 2100. Maybe the author was not aware of this method.

Finally, it looks like the program does not calculate the biorhythm. Instead it seems to return the day within a 23-, 28- and 33-days period. Maybe this was not possible dues to the 100-step limit. I think it could be done if the usual date-to-day-formula was used.

Edit: I do not have a HP65 to check it but I tried a biorhythm program based on the standard day-to-date formula. It required less than 90 steps.
