HP 41 behavior - polbit - 03-18-2023 01:13 PM I am very new to 41-series. Have been playing with programming a lot, but today I just did a simple loop that shows an increasing number, and don’t understand the behavior: Code:
This shows X 1 though 8 or so quickly, then slows down to a crawl - about 2 seconds between showing the next number. Same behavior if I just switch the Alpha section to a simple VIEW X. If I don’t show the number, it is of course very fast (well, relatively speaking ) Could someone educate me on why that is happening? RE: HP 41 behavior - ThomasF - 03-18-2023 03:03 PM Hi, Do you use a normal HP41, or something else? Like DM41X or simulator? Or do you have something connected to the 41, like HPIL or printer? I just tried on my HP41CX and I don't see the behavior you describe. Executing "TEST" shows (as expected when the calculator is in FIX 4 mode): Code: X=0,0200 (½sec pause) If a printer is attached (or IR module), this might explain the behavior, since after the printer-buffer is full the execution slows down to be able to print, but there is room for ~8 lines. I don't have a printer for my 41 to test with, but I have seen similar delays when printing a program on the DM41X (using the normal printer ROM and IR). The first ~8 lines goes very quickly, but after that is slows down quite noticable.

Didn't even think about it being and issue with the print buffer! Disabled thermal printer module and all is behaving as expected! |
