Hello there,

I am learning my way through Amiga assembler.
I want to "watch the changes in the registries as I make changes. Basically every time I click the left mouse button, it does something, I look at the registries and then so forth until the rts is met.

Unfortunately, it detects one click and ignores the others. It seems that right after the first detection how to clear something, but what/how I don't know. Any help would unblock my learning!

Code:
step1:

btst #6,$bfe001
bne step1

; make the first change to the registry
movea.l #$00000039,a0

step2:
btst #6,$bfe001
bne step2

move.b #$44,(a0)

step3:
btst #6,$bfe001
bne step3

move.b #$9B,$04(a0)

rts

Setup:
Asm One 1.18
FS-UAE
macOS

It just runs through. If you really wanted to go this way, also check for release of mousebutton.

Better, yet, use the debugger (ad) without all that mouse stuff.
