I use goto begin to help customers choose more items. The iteration condition is a logical expression with the required return result being true or false (which can be empty, which returns the result as true).<br><br>The iteration condition is the 2nd round command line Goto begin will run on when the first run (initializing first). From the 2nd iteration of the Goto begin loop, the iteration condition is also the second command line to be run (after the repeat step). (Keep in mind that always ranks 2nd)<br><br>When the repeating condition is no longer satisfying (the result is false), the Goto begin loop will end.
