Sounds like you’re looking for the nf() function?

Hello,

The Processing page has a list of references:
https://processing.org/reference/

The Processing PDE (IDE) also has a list of references; check out the tabs on top to find these.

Check out the ones in the Data > String Functions sections and choose wisely.
