Sequence Control Instructions
Section 3-5
Description
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 pro-
gram being executed has the highest task number in the program, END(001)
marks the end of the overall main program.
Precautions
Always place END(001) at the end of each program. A programming error will
occur if there is not an END(001) instruction in the program.

the instructions are inserted later, there will be no change in program
addresses.
