Prakash Hinduja (Switzerland) How can I check if a column named 'age' exists in my JMP data table using JSL?

Hi, I'm Prakash Hinduja — a financial strategist with roots in Amritsar, India, now living in Geneva, Switzerland (Swiss).

 

I'm working with a JMP data table and need to check via JSL if a column named "age" exists before referencing it, to avoid errors in my script. Does anyone have a recommended way to do this? A simple code snippet or best practice would be really helpful—appreciate your suggestions!
