Hello, and welcome to my very first tutorial, hope u all like it :
ok, here is the code, i will document it as we go along :
ld a,10000000b ; What the run indicator will look like, 11110000b is normal, 10101010b is pause...
ld (indicBusy),a ; Load ur new run indicator into the real run indicator
set indicRun,(IY + IndicFlags) ; Activate it! Cannot use the bcall, because it resets the run indicator to normal...
;
;
; Main Code Here...
;
;
ld a,busyNormal ; Reset the run indicator to normal, busyNormal is equated to 11110000b in the ti83plus.inc file
ld (indicBusy),a ; load the real one back in!
;at the end here, u could just use the bcall and it would reset it if u wanted... ENJOY! |

| Nice tutorial on indicators; still, I usually leave it off in asm programs. |

| Why even have a run indicator? It makes your program look like it was wrighten in basic. |

Not if you make it look different. :lol:
Is there also a way to make the run indicater go down instead of up?  That would be neat.
Oh, and nice tutorial btw! It's one of those things you never think of finding out. |

| to make it reverse, set an interrupt to change the pixels in the opposite order. |

| Correct me if I'm wrong, but the whole idea of this tutorial is to let the system routines do all the work. |

| no, not exactly, cause a system routine is the same thing as a bcall, and they reset the run indicator, but i guess u could say that, cause this is built in stuff... |

| di will still trun off the indicator by disabling maskable interrupts. |

the normal ti-interrupt handles the run indicator... here is a little thing i found in 83pa28d :
Code:
set indicOnly, (IY + indicFlags) ; Interrupt handler only checks run indicator (don't process APD™, blink the cursor, or scan for keys).
cool, eh? cant seem to see a use for it though... |

| I think it can be used the same as di with the exception that the run indicator still works. |

but, unless u wanted a special run indicator  , then this routine would be utterly useless! |
