Extracts one line of a multi-line string and sets that line in single-line String-type Data Item. The Line ID mut be an integer starting with zero. If the Line ID is not specified, or if a number outside the range is specified, the last line will be extracted.
Configs
A: Set Multiline String *#{EL}
B: Set Line ID (eg “0”)#{EL}
C: Select STRING DATA that stores Extracted Line (update) *

/*
Notes:
- When the process reaches the automated task, the Nth line in the multiline string is extracted.
- You should specify Line-ID `N` as a zero-based integer.
- If you want to extract the first line, specify "`0`".
APPENDIX:
- If the Line-ID contains commas, they will be removed and then parsed.
- Parsing depends on JavaScript `parseInt()`.
- If a line with only line breaks is specified, the single line data will be overwritten with an empty string.
Notes-ja:
- 案件がこの自動処理工程に到達した際、複数行文字列（候補行リスト）内の第N行を自動的に抽出します。
- 行ID `N` はゼロ始まりの整数で指定してください。
- もし先頭行を抽出したい場合は "`0`" を指定します。
APPENDIX-ja:
- 行IDにカンマ（桁区切り文字等）が存在する場合、除去された文字列が解析されます。
- 解析は JavaScript `parseInt()` に依存します。
- 改行のみの行が指定された場合には、単一行文字列データは空文字で上書きされます。
