(1) Definition
Main routine program is an entire program from the step 0 to the END or FEND instruction.
(2) Program operation
A main routine program executes its operations from the step 0 to the END or FEND instruction and then

When multiple programs are executed, the main routine program operation after execution of the END or FEND instruction
varies depending on the preset execution conditions. ( Section 2.3)
