All right, you've assembled your program and ran it. After watching your program to run for a while, you end its execution by hitting the RUN/STOP + RESTORE key combination. So, you end up in BASIC V2 to again ...
Because typing SYS32768 gets old really fast, here's a small code snippet you can use stop your program execution by hitting only the RESTORE key and also jump right back into TMP again without having to type anything.
; Place this code in the start of your program.
; The vanilla TMP start address is $8000 (32768).
; If you use TMP+REU, the address is different.
JUMPBACK = $8000
SEI
LDA #<JUMPBACK
STA $0318
LDA #>JUMPBACK
STA $0319
