(2) STOP and CONT instructions and operation of the Break ( Ctrl
+ C ) key
The program pauses (interrupts) when a STOP instruction is executed.
Also, if the Break ( Ctrl + C ) key is pressed while the program is being
executed, the program pauses (interrupts) in the same way as in the case of the
STOP instruction.
Execute the CONT instruction to resume the execution of a program that has
been paused (from the next instruction).
