Programs and number entry - Mike T. - 04-07-2008 I'd be interested in some additional information regarding the outcome of pressing a key when a program is running on the HP67, HP25C and HP29C in the table below. HP25C : Unknown - same as HP67?¹ After the current instruction (incuding a PAUSE). Many thanks. Mike T.

Re: Programs and number entry - Mad Dog ebaycalcnut - 04-07-2008 How about the HP-65?
Re: Programs and number entry - Les Bell - 04-07-2008 Dunno about the 10C, but the 16C is definitely the same as the 11C (I just checked). I'd bet the Voyagers are all the same. Best,

Re: Programs and number entry - Hal Bitton in Boise - 04-09-2008 Hi Mike,
At the risk of exposing my ignorance, what is an HP67A ?
Best regards, Hal
Re: Programs and number entry - Mike T. - 04-09-2008 Thanks for all the feedback, particularly with respect to the HP25 and HP67 (I'd seen the A suffix used elsewhere and included it here just to get all the text to line up!) Having established that for all these models any key halts program execution while a program is running. I'd like to clarify what happens when a key is pressed during a pause. For the HP10C, HP11C, HP25, and HP33C pressing a key while a pause instruction executes appears to just halt the program as before (the key stroke is not entered or executed). I believe (but cannot confirm) that the HP67/97 behave rather differently and would be interested in any additional information and in knowing what other models behave in the same way as the HP67/97 or were these two models unique? In particular I'd like to know what the HP29C does - is the same as the HP25 or does it behave like the HP67...?

Re: Programs and number entry - Hal Bitton in Boise - 04-09-2008 Yes indeed Mike...
If I press any key during a pause instruction while a program is executing, that key function is executed, and then program execution continues. This goes for shifted functions as well. I also noted that program execution will continue after the key is released, no matter how long the key was held. Re: Programs and number entry - Mike T. - 04-09-2008 I find it interesting that HP67 behaves differently from the HP29C. Given the hardware similarities between the two machines I'd half expected the new behaviour introduced by the HP67 to be present on the the HP29C as was introduced after the HP67. From your observations it would appear that the HP29C was intended to behave like the HP25 and later HP3x models... Mike T.
