I haven't been able to find a simple solution to this problem. I have a program that displays an image, then it waits for 2 before showing the next one. It goes for a loop, so I decided to use get key so the user can quit without using ON. However, the only time the calc can check to see if getKey=45 is when it is not in the paused wait. How can I fix this?
Code:
Repeat A=45
Axes off
getKey->A
BackgroundOn 1
Wait 2
BackgroundOn 2
Wait 2
BackgroundOn 3
Wait 2
BackgroundOn 4
Wait 2
End

Add more getKey->A's, as in one after each thing, and everywhere. It's stupid, but it works.

I tried this, but it still won't let the clear button end the program.
Code:
Repeat A=45
AxesOff
getKey→A
BackgroundOn 1
getKey→A
DispGraph
getKey→A
Wait 2
getKey→A
BackgroundOn 4
getKey→A
Wait 2
getKey→A
BackgroundOn 5
getKey→A
Wait 2
getKey→A
BackgroundOn 7
getKey→A
Wait 2
getKey→A
End
Ooooof. Stupid me. You need an If A=45 statement at the end telling it what to do when clear is pressed.

Do you mean like this?
Code:
Repeat A=45
AxesOff
getKey→A
BackgroundOn 1
getKey→A
DispGraph
getKey→A
Wait 2
getKey→A
BackgroundOn 4
getKey→A
Wait 2
getKey→A
BackgroundOn 5
getKey→A
Wait 2
getKey→A
BackgroundOn 7
getKey→A
Wait 2
getKey→A
End
If A=45
Return
This isn't working, and neither does the same bit before the end.
All If statements have to be closed with an 'End'. Use ClrHome/Stop instead of Return. (Return is for returning from another subprogram)

I thought that 'End' was only needed if the if statement was more than two lines. Either way, I modified it to address both of these points, and "Clear" still has no effect,
Code:
Repeat A=45
AxesOff
getKey→A
BackgroundOn 1
getKey→A
DispGraph
getKey→A
Wait 2
getKey→A
BackgroundOn 4
getKey→A
Wait 2
getKey→A
BackgroundOn 5
getKey→A
Wait 2
getKey→A
BackgroundOn 7
getKey→A
Wait 2
getKey→A
If A=45
Stop
End
If A=45
Stop
End

End
If A=45
Stop
End
Try this:
Code:
ClrHome
AxesOff
DispGraph
While A!=45
BackgroundOn 1
getKey->K
Wait 2
getKey->K
BackgroundOn 2
getKey->K
Wait 2
getKey->K
BackgroundOn 3
getKey->K
End
ClrHome
Stop
If statements only need an End if they have are an If-Then. If-Then can span multiple lines.
Try something like this:
Code:
Repeat A=45
0->B
Repeat B=20 or A=45
B+1->B
getKey->A
End
BackgroundOn 1
0->B
Repeat B=20 or A=45
B+1->B
getKey->A
End
BackgroundOn 2
0->B
Repeat B=20 or A=45
B+1->B
getKey->A
End
BackgroundOn 3
getKey->A
Edit the number B is compared to to make your delay longer or shorter.
I tried modifying to meet what dankcaclutaltorbro said, but now when you press clear, all it does is move on to the next image, not quit.
Code:
Repeat A=45
AxesOff
0->B
Repeat B=75 or A=45
DispGraph
B+1->B
getKey->A
End
BackgroundOn 1
0->B
Repeat B=75 or A=45
DispGraph
B+1->B
getKey->A
End
BackgroundOn 4
0->B
Repeat B=75 or A=45
DispGraph
B+1->B
getKey->A
End
BackgroundOn 5
0->B
Repeat B=75 or A=45
DispGraph
B+1->B
getKey->A
End
BackgroundOn 7
getKey->A
End
