FAST/SLOW status

Post by cdmackay »

hi, is there any way to tell whether the current state is FAST or SLOW?

Sure. XEQ "FAST" and then if it runs faster, it was in SLOW mode. :lol:

But if you mean in a program, no there isn't, because the 41CX OS had no way to check that (since there was no FAST).

It is possible that there is an unused (or irrelevant) System Flag that could be repurposed for this, it will take some digging.

Wish I had thought of that... ;)

heh :)

thanks; it wasn't so much for program use, but more so I could check if I'd accidentally left it on SLOW.

If that state is visible outside the emulator, e.g. DMCP, it could appear in the alternate DSP area, perhaps?

I don't know where the speed control takes place (probably in the emulation layer), but I think [XEQ] "FAST" is fewer keystrokes... 8-)

quite!

although I meant a symbol/glyph that could appear on the DSP screen (that's only two keystrokes) or even the top line (no keystrokes)

I just know I'm going to fret about this, even though I'm rarely, if ever, likely to XEQ SLOW :)

Aha... It took a moment to grasp what you meant by the "DSP screen" - it's been called SI (System Info) View internally. The "DSP" key label was intended to be short for Display, as it's used to toggle display views in both Calculator and PRGM modes.

Anyhow, now I get it.

Let's see if this is an issue for lots of folks; if so we can check into options for addressing it.

Nope...not just you. I'd also like to know, via the status screen, if the DM41X is in the fast or slow mode.

Re: FAST/SLOW status - Sluggish Counter

Post by anetzer »

So,

1. Updated the DM41X to the latest firmware and program package yesterday.
2. Did a Reset (Memory Lost).
3. Entered a short counting program:
  • LBL'TEST
    FAST
    1
    ENTER^
    ENTER^
    ENTER^
    LBL 00
    VIEW X
    +
    GTO 00
    END
When I XEQ TEST and the program starts. But pressing R/S takes a long time to register and stop the program, as if the interrupts where really not working.

Running and stopping the program again did not really change anything: Program starts immediately but often takes several seconds to stop with depressed R/S.

Also:
When I ran it, it crept really slow. I even had the impression it ran faster when I stopped it, XEQ SLOW and pressed R/S. Plus it does not run smoothly: It seems to halt between numbers at times, so there is no smooth rhythm to the counting at all.

Did I miss something, Can anybody recreate that?

I entered your program in my DM41X but it runs smoothly and I don't see any issue when stopping with R/S. When switching to SLOW I noticed the display blinking already reported but not a faster execution.

Btw on the DM41X you can replace the 3 ENTER^ on lines 4,5,6 by FILL which is part of the additional instructions included in the patched mainframe ROMS as documented in the manual.

EDIT: one additional note related to FAST/SLOW. I have loaded the default CST configuration file which assigns FAST and SLOW to respectively shift up and shift down arrows. This works fine in run mode but in PRGM mode I've discovered that shift up and shift down arrows have a different function than the one assigned by CST: they go respectively to the top and the end of the current program. A nice feature which I've not found documented in the manual unless I missed it.
