It is possible to start a new program using the ZSTART instruction to specify any task
area while executing multitask processing.
Before starting a program using the ZSTART instruction,
set the applicable task area to 'START', 'BOOT', 'IT', or 'ON' using the SET command in
system mode. A program cannot be started in the task area using the ZSTART instruction
if the task area is set to 'OFF'.
There are two ways to start a program using the ZSTART instruction.
1) Read a program from a memory card to the specified task area and start it.
