There are 2 ways of terminating a program in RPL.
'''IF''' problem '''THEN''' HALT '''END'''
Here, nothing is cleaned up: local variables are still existing and a step-by-step execution is possible thanks to the <code>SST</code> instruction, typically for debugging. Once the bug found, a manual cleanup must be done through the <code>KILL</code> instruction.
If a full termination with cleanup is desired, it must be written:
'''IF''' problem '''THEN''' ABORT '''END'''
All currently running processes are then terminated, all local variables are discarded and control is given back to the user.
