Reading from multiple textfields and saving into .txt file

Processing Libraries
12

this might be one way to do it.

We gather the inputs in one String infos but separate them by #
When saving we use split and then save

It makes files like Bob.txt, containing

Bob
1220

For each person / name a new file is created.

Remark
Alternatively, we could make one big file names.txt, more like a csv file containing

Bob,120
Ann,2220
Paul,34
