Invisible Pause in RPN-65 program

[Matt Agajanian]

Hi all.

For those of you familiar with Willy Kunz’s RPN-65 app, I’m trying to figure out how and why a sample program I made pauses during the running of the program.

Here’s the program.

001: 23 LBL
002: 11 A
003: 31 f
004: 43 REG
005: 33 08 STO 8

LBL 0:
006: 23 LBL
007: 00 0
008: 02 2
009: 34 08 RCL 8
010: 35 g
011: 05 yˣ
012: 33 STO
013: 61 +
014: 01 1
015: 35 g
016: 83 DSZ
017: 22 GTO [006]
018: 00 0
019: 01 1
020: 33 STO
021: 61 +
022: 01 1
023: 34 01 RCL 1
024: 84 R/S

As you can see, there is no Pause instruction in the listing. Yet, after step 11, the program pauses to reveal the result of the 2^(R8) instruction. I don’t mind the pause. But, since I didn’t include a Pause instructions and there is no Pause operation on the 65, how could the program execute a Pause?

Thanks

That looks like a lot of work for an old calculator to be doing, maybe like me, it is just stopping for a much needed rest. B^)

Okay. I get that.

OTOH.

Just loaded and ran the program today (in Vintage mode), and the program ran without pausing and instead showed the usual diode shuffling of the display during the run of the program.

Hmm?!

I just key-in the code today on a vintage Hewlett-Packard 65 and the program ran without pausing, displaying the usual red shuffling during the computations. ( y^x doesn't appear to be an heavy work )

Humm, ...
... is the Willy Kunz’s RPN-65 app running on the last model of the current Apple device ?

Same obsolete models or previous versions of Apple systems have an on-growing tendance to pause time to time in order to incite the user to upgrade to the newest.

To answer your question, I’m using v3.4.1 of RPN-65 on an 256GB iPhone X running iOS 15.1.
