Removes the first line from a multiline string so there is one line less than the original string. By placing it in a loop or a recursive workflow the data list can be processed sequentially.
Configs
A: Set Multiline String *#{EL}
B: Select STRING DATA that stores extracted First Line (update) *
C: Select STRING DATA that stores Modified Multiline (update) *

- 複数行文字列A内の空行（改行コードのみの行）は、あらかじめ削除されます
- 複数行文字列Aが空文字列の場合（となる場合）、エラーとなります
