Is there a consolidated errata for HP calculator documentation?
Hi, I am still learning to program on free42.

I noticed this in page 39 of HP-42S RPN Scientific Programming Examples and Techniques
Edition 1 July 1988.

DISPL calculates the displacement at successive time intervals from ¢ = 0
to t = t; . It builds a loop counter of the form fffcc by prompting you for
====
the value of ¢;, and for the value of STEP (the value of the time interval).
t; becomes the fff portion of the counter and STEP becomes the ii portion
of the counter.

Could the .fffcc be a typo? I was expecting .fffii .

If someone could point me to such a repository of errata, it would help eliminate further enquiries.

There is a newer version of that manual available here:

https://literature.hpcalc.org/items/934

However it does not correct that alleged typo, which seems to be the case.

There is a formal errata for the original User Manual here, but I've never seen one for the Programming Examples manual:

https://literature.hpcalc.org/items/926

Thanks. Some things are still bewildering like
13 STO IND "COUNT"
14 ISG "COUNT"
at page 44.

I had to find another forum entry that mentioned
that only the integer portion of COUNT was used
for STO IND. I have no idea what mechanism
accomplishes this without modifying COUNT.

TONE can handle IND but that was not
mentioned in the table on page 72 of
the owner's manual.

The only way to find out what can pair with IND
is trial and error as page 74 demonstrates:

2. Press (-]. If the calculator displays IND __
after the function name, skip to step 4.
