First Call是一個有趣的功能,
在程式碼區塊(如Loop結構)執行的第一次會傳出一個TRUE值,
但之後便會傳出False,
因此如果想在執行程式迴圈的第一次做特別或獨立的功能,
First call會是一個不錯而簡單的選擇。
First Call is the funny function which return true value when diagram block (like Loop structure) is executed at first time, then return false value at the rest time.
If you want to make some special or independent function at first excecution time, First Call is the good and simple choice.

建議在highlight execution下看程式執行的流程,會更清楚知道First call的功能
Recommand to see the processing by using "highlight excecution" functuin, You can realize how "first call" work.
