Problem Statement

Show the syntax for a complete stoppage of a program inside a   conditional. This includes all threads/processes which are part of your program. Explain the cleanup (or lack thereof) caused by the termination (allocated memory, database connections, open files, object finalizers/destructors, run-on-exit hooks, etc.).
Unless otherwise described, no special cleanup outside that provided by the operating system is provided.

Let's start with the solution:

PROC Main()
  DO
    IF Rand(0)=10 THEN
      PrintE("Terminate program by Break() procedure")
      Break()
    FI
  OD
  PrintE("This is a dead code")
RETURN
