Issue with using array after splitTokens()

Processing Electronics (Arduino, etc.)
5

At the moment I am working on basically copying the code line by line but implementing it for a different purpose. This is how I’ve learned code and I guess it’s working

But question…there are some variable names/objects (not like Java objects) that I want to know…

What does the following mean:

  • recs
  • diagp
  • ["+i+"] especially this, I think it adds the index?

Why specifically these variable names? Just wanted to know.

Also in the draw() function, I am a bit lost in terms of the language. You execute the function anyway whether getrecord is true or false?!?!

if(getrecord). // statements`
//somewhere later, with statements
getrecord = true;`
//later again...
getrecord = false;

Thanks
