VI Job Cycle Option - what is this for?

SUGGESTED

Can someone explain the purpose of the Cycle Option in VI.  I have read what documentation I can find but want a "real world" explanation of how it is used.

I am hoping it will cause my VI Job to complete.  I have a bat file that is run from Windows Task Scheduler but it opens and closes the bat file which then closes/interrupts my VI job.  Will the Cycle make it run after the bat file has initiated it and closed?

Thanks. Jacquie
