END(001)
Indicates the end of a program.
END(001) completes the execution of a program for
that cycle. No instructions written after END(001)
will be executed. Execution proceeds to the
program with the next task number. When the
program being executed has the highest task
number in the program, END(001) marks the end of
the overall main program.
