HP15C programm into HP41; HOWTO

Postby floppy_stuttgart » Thu Oct 07, 2021 1:32 pm

Hello,
I was searching a RPN command comparison/summary for transferring HP15C RPN programs into HP41; example https://www.hpmuseum.org/forum/thread-17003-page-2.html
Has anybody anything?
Especially the
RCL "+*-/" nn
are new for me. Perhaps other commands will be discovered.

Eric Rechlin offers the HP-15C Owner's Handbook in several languages. Recall Arithmetic is described in 'Section 3: The Memory Stack, LAST X, and Data Storage.'
Perhaps other commands will be discovered.

Sure. If you are new to a subject reading the manual may help.

You referenced a thread about "Perimeter of the Ellipse". If you are interested in a HP41 version of the algorithm in question, just once more, here it is.

Thanks. Looks like SandMath has the HP15C stuff.
I will include the SandMath (HP-15 stuff) into my HP41 codes.

Nope. Only differing and incomplete.
Examples: RAND is the same linear congruential generator (LCG) as in PPC-ROM and CCD Module, ist is not a full period LCG. So it differs from the one in HP-15C.
In addition, HP-15C offers a RCL RAN# (not found in SandMath, at least not at first glance). But it is in the latest update of my Voyagers' Pseudorandom Number Generator.

Be sure to look into the same author's (Angel's) 41z module.
